CS43L42

Low Voltage, Stereo DAC with Headphone Amp

Features

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.

1.8 to 3.3 Volt supply

24-Bit conversion / 96 kHz sample rate

96 dB dynamic range at 3 V supply

-85 dB THD+N

Low power consumption

Digital volume control

• 96 dB attenuation, 1 dB step size

Digital bass and treble boost

• Selectable corner frequencies

• Up to 12 dB boost in 1 dB increments

Peak signal limiting to prevent clipping

De-emphasis for 32 kHz, 44.1 kHz, and 48 kHz

Headphone amplifier

• up to 25 mW_rmspower output into 16 Ω load*

• 25 dB analog attenuation and mute

• Zero crossing click free level transitions

ATAPI mixing functions

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. The

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.
