The TS482 is a dual audio power amplifier able to
drive a 16 or 32鈩?stereo headset down to low volt-
ages.
It鈥檚 delivering up to 100mW per channel (into 16鈩?/div>
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.
