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.
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.
The CS53L32A contains adjustable analog gain, a 2:1
input mux, and digital attenuation.
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.
