CS43L43

Low Voltage, Stereo DAC with Headphone Amp

Features

Description

The CS43L43 is a complete stereo digital-to-analog out-

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

analog filtering, volume control, and a headphone ampli-

fier, in a 16-pin TSSOP package.

16-Pin TSSOP Package

1.8 to 3.3 Volt Supply

24-Bit Conversion / 96 kHz Sample Rate

94 dB Dynamic Range at 3 V Supply

-85 dB THD+N at 1.8 V Supply

Low Power Consumption

The CS43L43 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.

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

The CS43L43 contains on-chip digital bass and treble

boost, peak signal limiting and de-emphasis. The

CS43L43 operates from a +1.8 V to +3.3 V supply and

consumes only 16 mW of power with a 1.8 V supply.

These features are ideal for portable CD, MP3 and MD

players and other portable playback systems that require

extremely low power consumption.

• up to 22 mW_rmsPower Output into 16 Ω Load*

• 25 dB Analog Attenuation and Mute

• Zero Crossing Click-free Level Transitions
