OUT (1) 1 2 3 4 8 7 6 5 Vcc OUT (2) VIN - (2) VIN + (2) The TS482 is a dual audio power amplifier able to drive a 16 or 32 stereo headset down to low voltages.

It is delivering up to 100mW per channel (into 16 loads) of continuous average power with 0.1% THD+N from a 5V power supply. The unity gain stable TS482 can be configured by external gain-setting resistors. VIN - (1) VIN + (1) GND T
