CS53L32A

Low Voltage, Stereo A/D Converter

FEATURES

DESCRIPTION

The CS53L32A is a highly integrated, 24-bit, 96 kHz au-

dio ADC providing stereo analog-to-digital converters

using delta-sigma conversion techniques. This device in-

cludes volume control and line level inputs in a 20-pin

TSSOP package.

z 20-Pin TSSOP package

z 1.8 V to 3.3 V supply

z 24-bit conversion / 96 kHz sample rate

z 98 dB dynamic range at 3 V supply

z -88 dBFS THD+N

The CS53L32A is based on delta-sigma modulation al-

lowing infinite adjustment of the sample rate between

2 kHz and 100 kHz simply by changing the master clock

frequency.

z Low power consumption

– 11 mW at 1.8 V

z Up to 32 dB gain

The CS53L32A contains adjustable analog gain, a 2:1

input mux, and digital attenuation.

– 20 dB gain step

– 12 dB variable input gain, 1 dB steps

– Changes made at zero crossings

z Stereo inputs

z Digital volume control

– 96 dB attenuation, 1 dB step size

– Mute

The CS53L32A operates from a +1.8 V to +3.3 V supply.

These features are ideal for portable MP3 players, MD

recorders/players, digital camcorders, PDAs, set-top

boxes, and other portable systems that require extreme-

ly low power consumption in a minimum of space.

– Soft ramping
