Low Voltage, Stereo, A/D Converter

The CS53L32A is a highly integrated, 24-bit, 96 kHz audio A/D converter providing stereo, analog-to-digital converters using Delta-Sigma conversion techniques.

The CS53L32A is based on Delta-Sigma modulation, allowing 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 to 3.3V supply. These features are ideal for portable MP3 players, mini-disc recorders/players, digital camcorders, PDAs, set-top boxes, and other portable systems that require extremely low power consumption in a minimum of space.
