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 16Ω or a 32Ω stereo headset.

Features
■ Pop and click noise protection circuitry
■ Operating range from VCC = 2.2V to 5.5V
