103 dB A/D Converter with 6:1 Mux

The CS5346 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. 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. Integrated level translators allow easy interfacing between the CS5346 and other devices operating over a wide range of logic levels.


  • Stereo 6:1 input multiplexer
  • Programmable gain amplifier (PGA)
  • Stereo microphone inputs
  • Direct interface with 3.3 V to 5 V logic levels
