Description

The CS43L42 is a complete stereo digital-to-analog out-

put system including interpolation, 1-bit D/A conversion,

analog filtering, volume control, line level outputs, and a

headphone amplifier, in a 24-pin TSSOP package.

The CS43L42 is based on delta-sigma modulation,

where the modulator output controls the reference volt-

age input to an ultra-linear analog low-pass filter. This

architecture allows infinite adjustment of the sample rate

between 2 kHz and 100 kHz simply by changing the

master clock frequency.

The CS43L42 contains on-chip digital bass and treble

boost, peak signal limiting, and de-emphasis.

CS43L42 operates from a +1.8 V to +3.3 V supply and

consumes only 16 mW of 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.
