The CS5346 is an audio A/D converter (ADC) that integrates an analog multiplexer, programmable gain amplifier, and stereo audio ADC. The CS5346 performs stereo A/D conversion of 24-bit serial values at sample rates up to 192 kHz.
A 6:1 stereo input multiplexer is included for selecting between line-level and microphone-level inputs. The microphone input path includes a +32 dB gain stage and a low-noise bias voltage supply. The PGA is available for line or microphone inputs and provides gain/attenuation of ±12 dB in 0.5 dB steps.
The output of the PGA is followed by an advanced 5th order, multi-bit delta sigma modulator and digital filtering/decimation. Sampled data is transmitted by the serial audio interface at rates from 8 kHz to 192 kHz in either Slave or Master Mode.
Integrated level translators allow easy interfacing between the CS5346 and other devices operating over a wide range of logic levels.
