Features, Applications

FEATURES No external components No switch-on/off clicks Good overall stability Low power consumption Short circuit proof ESD protected on all pins. GENERAL DESCRIPTION The is a mono output amplifier contained a 9 pin SIL medium power package (SOT110). The device is designed for battery-fed portable mono recorders, radios and television. QUICK REFERENCE DATA SYMBOL PARAMETER supply voltage Gv Ip THD output power internal voltage gain total quiescent current total harmonic distortion Vp=11 V; RL=# Po=0,5 W CONDITIONS MIN. 2.5 39 TYP. MAX. 18 UNIT mA %

FUNCTIONAL DESCRIPTION The is a mono output amplifier, designed for battery-fed portable radios and mains-fed equipment such as television. For space reasons there is a trend to decrease the number of external components. For portable applications there is also a trend to decrease the number of battery cells, but still a reasonable output power is required. The ILA7056SH fulfills both of these requirements. It needs no peripheral components, because it makes use of the BridgeTied-Load (BTL) principle. Consequently it has, at the same supply voltage, a higher output power compared to a conventional Single Ended output stage. It delivers an output power 1 W into a loudspeaker load 8 W with 6 V supply 3 W into 16 W loudspeaker 11 V without need of an external heatsink. The gain is internally fixed at 40 dB. Special attention is given to switch-on/off click suppression, and it has a good overall stability. The load can be short circuited at all input conditions.

Notes to the characteristics 1. With a load connected to the outputs the quiescent current will increase, the maximum value of this increase being equal to the DC output offset voltage divided by RL. 2. The noise output voltage (RMS value) is measured with 5 kW unweighted to 20 kHz). 3. The noise output voltage (RMS value) = 500 kHz is measured with 0 W and bandwidth = 5 kHz. With a practical load (RL = 200 mH) the noise output current is only 50 nA. 4. The ripple rejection is measured with 0 W and to 10 kHz. The ripple voltage (200 mV) is applied to the positive supply rail. = 5 kW.
