DESCRIPTION
The OPT301 is an opto-electronic integrated circuit
containing a photodiode and transimpedance
amplifier on a single dielectrically isolated chip. The
transimpedance amplifier consists of a precision FET-
input op amp and an on-chip metal film resistor. The
0.09 x 0.09 inch photodiode is operated at zero bias for
excellent linearity and low dark current.
The integrated combination of photodiode and
transimpedance amplifier on a single chip eliminates
the problems commonly encountered in discrete de-
signs such as leakage current errors, noise pick-up and
gain peaking due to stray capacitance.
The OPT301 operates over a wide supply range (±2.25
to ±18V) and supply current is only 400µA. It is
packaged in a hermetic TO-99 metal package with a
glass window, and is specified for the –40°C to 85°C
temperature range.

DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with ap-
propriate precautions. Failure to observe proper handling and
installation procedures can cause damage.
ESD damage can range from subtle performance degradation
to complete device failure. Precision integrated circuits may
be more susceptible to damage because very small parametric
changes could cause the device not to meet its published
specifications.

OPT301
APPLICATIONS INFORMATION
Figure 1 shows the basic connections required to operate the
OPT301. Applications with high-impedance power supplies
may require decoupling capacitors located close to the
device pins as shown. Output is zero volts with no light and
increases with increasing illumination.
If your light source is focused to a small area, be sure that
it is properly aimed to fall on the photodiode. If a narrowly
focused light source were to miss the photodiode area and
fall only on the op amp circuitry, the OPT301 would not
perform properly. The large (0.090 x 0.090 inch) photodiode
area allows easy positioning of narrowly focused light
sources. The photodiode area is easily visible—it appears
very dark compared to the surrounding active circuitry.
The incident angle of the light source also affects the
apparent sensitivity in uniform irradiance. For small incident
angles, the loss in sensitivity is simply due to the smaller
effective light gathering area of the photodiode (proportional
to the cosine of the angle). At a greater incident angle, light
is reflected and scattered by the side of the package. These
effects are shown in the typical performance curve
“Response vs Incident Angle.”
DARK ERRORS
The dark errors in the specification table include all sources.
The dominant error source is the input offset voltage of the
op amp. Photodiode dark current and input bias current of
the op amp are approximately 2pA and contribute virtually
no offset error at room temperature. Dark current and input
bias current double for each 10°C above 25°C. At 70°C, the
error current can be approximately 100pA. This would
produce a 1mV offset with RF = 10MΩ. The OPT301 is
useful with feedback resistors of 100MΩ or greater at room
temperature. The dark output voltage can be trimmed to
zero with the optional circuit shown in Figure 3.
FIGURE 1. Basic Circuit Connections.
Photodiode current, ID, is proportional to the radiant power
or flux (in watts) falling on the photodiode. At a wavelength
of 650nm (visible red) the photodiode Responsivity, RI, is
approximately 0.45A/W. Responsivity at other wavelengths
is shown in the typical performance curve “Responsivity vs
Wavelength.”
The typical performance curve “Output Voltage vs Radiant
Power” shows the response throughout a wide range of
radiant power. The response curve “Output Voltage vs
Irradiance” is based on the photodiode area of 5.23 x 10–6m2.
The OPT301’s voltage output is the product of the photodiode
current times the feedback resistor, (IDRF). The internal
feedback resistor is laser trimmed to 1MΩ ±2%. Using this
resistor, the output voltage responsivity, RV, is approximately
0.45V/µW at 650nm wavelength.
An external resistor can be used to set a different voltage
responsivity. For values of RF less than 1MΩ, an external
capacitor, CEXT, should be connected in parallel with RF (see
Figure 2). This capacitor eliminates gain peaking and prevents
instability. The value of CEXT can be read from the table in
Figure 2.
LIGHT SOURCE POSITIONING
The OPT301 is 100% tested with a light source that uniformly
illuminates the full area of the integrated circuit, including
the op amp. Although all IC amplifiers are light-sensitive to
some degree, the OPT301 op amp circuitry is designed to
minimize this effect. Sensitive junctions are shielded with
metal, and differential stages are cross-coupled. Furthermore,
the photodiode area is very large relative to the op amp input
circuitry making these effects negligible.

OPT301
When used with very large feedback resistors, tiny leakage
currents on the circuit board can degrade the performance of
the OPT301. Careful circuit board design and clean assembly
procedures will help achieve best performance. A “guard
trace” on the circuit board can help minimize leakage to the
critical non-inverting input (pin 2). This guard ring should
encircle pin 2 and connect to Common, pin 8.
DYNAMIC RESPONSE
Using the internal 1MΩ resistor, the dynamic response of
the photodiode/op amp combination can be modeled as a
simple R/C circuit with a –3dB cutoff frequency of 4kHz.
This yields a rise time of approximately 90µs (10% to 90%).
Dynamic response is not limited by op amp slew rate. This
is demonstrated by the dynamic response oscilloscope
photographs showing virtually identical large-signal and
small-signal response.
Dynamic response will vary with feedback resistor value as
shown in the typical performance curve “Voltage Output
Responsivity vs Frequency.” Rise time (10% to 90%) will
vary according to the –3dB bandwidth produced by a given
feedback resistor value—
where:
tR is the rise time (10% to 90%)
fC is the –3dB bandwidth
LINEARITY PERFORMANCE
Current output of the photodiode is very linear with radiant
power throughout a wide range. Nonlinearity remains below
approximately 0.02% up to 100µA photodiode current. The
photodiode can produce output currents of 1mA or greater
with high radiant power, but nonlinearity increases to several
percent in this region.
This excellent linearity at high radiant power assumes that
the full photodiode area is uniformly illuminated. If the light
source is focused to a small area of the photodiode,
nonlinearity will occur at lower radiant power.
NOISE PERFORMANCE
Noise performance of the OPT301 is determined by the op
amp characteristics in conjunction with the feedback
components and photodiode capacitance. The typical
performance curve “Output Noise Voltage vs Measurement
Bandwidth” shows how the noise varies with RF and measured
bandwidth (1Hz to the indicated frequency). The signal
bandwidth of the OPT301 is indicated on the curves. Noise
can be reduced by filtering the output with a cutoff frequency
equal to the signal bandwidth.
Output noise increases in proportion to the square-root of the
feedback resistance, while responsivity increases linearly
with feedback resistance. So best signal-to-noise ratio is
achieved with large feedback resistance. This comes with
the trade-off of decreased bandwidth.
The noise performance of a photodetector is sometimes
characterized by Noise Effective Power (NEP). This is the
radiant power which would produce an output signal equal
to the noise level. NEP has the units of radiant power
(watts). The typical performance curve “Noise Effective
Power vs Measurement Bandwidth” shows how NEP varies
with RF and measurement bandwidth.

(1) The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may
reference these types of products as "Pb-Free".
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based
flame retardants must also meet the <=1000ppm threshold requirement.
(3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.
(5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation
of the previous line and the two combined represent the entire Device Marking for that device.
(6) Lead finish/Ball material - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead finish/Ball material values may wrap to two
lines if the finish value exceeds the maximum column width.
