1 / 40 page Copyright © Cirrus Logic, Inc. 2004 (All Rights Reserved) http://www.cirrus.com FEATURES 20-Pin TSSOP package 1.8 V to 3.3 V supply 24-bit conversion / 96 kHz sample rate 98 dB dynamic range at 3 V supply -88 dBFS THD+N Low power consumption –11 mW at 1.8 V Up to 32 dB gain – 20 dB gain step – 12 dB variable input gain, 1 dB steps – Changes made at zero crossings Stereo inputs Digital volume control – 96 dB attenuation, 1 dB step size –Mute – Soft ramping 2:1 Input mux 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.
