CS43L42 Summary of contents
Page 1
... The CS43L42 contains on-chip digital bass and treble boost, peak signal limiting, and de-emphasis. CS43L42 operates from a +1 +3.3 V supply and consumes only power with a 1.8 V supply with the line amplifier powered-down. These features are ideal for portable CD, MP3 and MD players and other portable playback systems that require extremely low power consumption ...
