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 Ω or a 32 Ω stereo headset. Capable of descending to low voltages, it delivers up to 31mW 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.
