CS53L21 Datasheet

CS53L21 Stereo Analog-to-Digital Converter

The CS53L21 is a highly integrated, 24-bit, 96-kHz, low power stereo A/D. Based on multibit, delta–sigma modulation, it allows infinite sample rate adjustment between 4 kHz and 96 kHz. The ADC offers many features suitable for low power, portable system applications. The ADC input path allows indepe.
