CS53L32A Datasheet | Cirrus Logic

FEATURES z 20-Pin DESCRIPTION The CS53L32A is a highly integrated, 24-bit, 96 k Hz audio ADC providing stereo analog-to-digital converters using delta-sigma conversion techniques. This device includes volume control and line level inputs in a 20-pin TSSOP package. The CS53L32A is based on delta-sigma modulation allowing infinite adjustment of the sample rate between 2 k Hz and 100 k Hz 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 extremely low power consumption in a minimum of space.
