CS5346

The CS5346 integrates an analog multiplexer, programmable gain amplifier, and stereo audio analog-to-digital converter. The CS5346 performs stereo analog-to-digital (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. CS5346 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 CS5346 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.
