Description

The TS488/9 is an enhancement of TS486/7 that eliminates pop and click noise and reduces the number of external passive components.

The TS488/9 is a dual audio power amplifier capable of driving, in single-ended mode, either a 16 or a 32 stereo headset.

Capable of descending to low voltages, it delivers up to 31mW per channel (into 16 loads) of continuous average power with 0.1% THD+N in the audio bandwidth from a 2.5V power supply.

An externally-controlled standby mode reduces the supply current to 10nA (typ.). The unity gain stable TS488/9 is configured by external gainsetting resistors.
