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.
