Applications

This audio IC was developed for notebook PCs and allows major reduction of amp circuit board area. (To

conform to PC98, includes built-in speaker drive amp, headphone amp, line amp. stereo/monaural switching,

DC voltage control electronic volume, watchdog, logic control function.)

(1) Speaker amp: Stereo BTL output 0.7W (when V

(2) Electronic volume control (-60 ~ +20dB). THD = 0.5% (when P

(4) Line amp: Mixes 4 inputs ( 2ch signals and outputs on 3 outputs ( 2ch. Stereo/monaural switching

(5) Microphone amp: Switch pin selects 1 of 4 inputs

(6) Logic control: Speaker, headphone and line amp (including microphone amp and mix amp) logic
