7 / 15 page Detailed Description Converter Operation The MAX1157/MAX1159/MAX1175 use a successive- approximation (SAR) conversion technique with an inherent track-and-hold (T/H) stage to convert an analog input into a 14-bit digital output. Parallel outputs provide a high-speed interface to microprocessors (µPs). The Functional Diagram at the end of the data sheet shows a simplified internal architecture of the MAX1157/ MAX1159/MAX1175. Figure 3 shows a typical applica- tion circuit for the MAX1157/MAX1159/MAX1175. Analog Input Input Scaler The MAX1157/MAX1159/MAX1175 have an input scaler which allows conversion of true bipolar input voltages and input voltages greater than the power supply, while operating from a single +5V analog supply. The input scaler attenuates and shifts the analog input to match the input range of the internal DAC. The MAX1157 has a unipolar input voltage range of 0 to +10V. The MAX1175 input voltage range is ±5V while the MAX1159 input voltage range is ±10V. Figure 4 shows the equivalent input circuit of the MAX1157/ MAX1159/MAX1175. This circuit limits the current going into or out of AIN to less than 1.8mA. 14-Bit, 135ksps, Single-Supply ADCs with Bipolar Analog Input Range _______________________________________________________________________________________ 7 Pin Description (continued) PIN NAME FUNCTION 15 REFADJ Reference Buffer Output. Bypass REFADJ with a 0.1µF capacitor to AGND for internal reference mode. Connect REFADJ to AVDD to select external reference mode. 16 REF Reference Input/Output. Bypass REF with a 10µF capacitor to AGND. REF is the external reference input when in external reference mode. 17 RESET Reset Input. Logic high resets the device. 18 CS Convert Start. The first falling edge of CS powers up the device and enables acquisition when R/C is low. The second falling edge of CS starts conversion. The third falling edge of CS loads the result onto the bus when R/C is high. 19 DGND Digital Ground 20 DVDD Digital Supply Voltage. Bypass with a 0.1µF capacitor to DGND. 21, 22 N.C. No Connection. Make no connection to these pins. 23 D0 Three-State Digital Data Output (LSB) 24 D1 Three-State Digital Data Output 25 D2 Three-State Digital Data Output 26 D3 Three-State Digital Data Output 27 D4 Three-State Digital Data Output 28 D5 Three-State Digital Data Output Figure 1.
