Description

The TS488 is a dual audio power amplifier capable of driving, in single-ended mode,

either a 16 Ω or a 32 Ω stereo headset.

The TS488 eliminates pop and click noise and reduces the number of required

external passive components.

Capable of descending to low voltages, it delivers up to 31 mW per channel (into 16

Ω loads) of continuous average power with 0.1% THD+N in the audio bandwidth from

a 2.5 V power supply.

An externally-controlled standby mode reduces the supply current to 10 nA (typ.).

The unity gain stable is configured by external gain-setting resistors.
