The TS488/9 is an enhancement of TS486/487 that eliminates pop & click noise. It is a dual audio power amplifier capable of driving, in single-ended mode, either a 16Ω or a 32Ω stereo headset.
It delivers up to 31mW per channel (into 16Ω 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 (typical). The TS488/9 is unity gain stable and is configured by external gain-setting resistors.
