CS5346 103-dB, 192-kHz, Stereo Audio ADC with 6:1 Input Mux ADC Features General Description Multi-bit DeltaSigma Modulator The CS5346 integrates an analog multiplexer, program- mable gain amplifier, and stereo audio analog-to-digital 103 dB Dynamic Range converter. The CS5346 performs stereo analog-to-digi- -95 dB THD+N tal (A/D) conversion of 24-bit serial values at sample Stereo 6:1 Input Multiplexer rates up to 192 kHz. Programmable Gain Amplifier (PGA) A 6:1 stereo input multiplexer is included for selecting 12 dB Gain, 0.5-dB Step Size between line-level and microphone-level inputs. The Zero-crossing, Click-free Transitions microphone input path includes a +32 dB gain stage and a low-noise bias voltage supply. The PGA is avail- Stereo Microphone Inputs able for line or microphone inputs and provides +32 dB Gain Stage gain/attenuation of 12 dB in 0.5 dB steps. Low-noise Bias Supply The output of the PGA is followed by an advanced 5th- Up to 192 kHz Sampling Rates order, multi-bit delta-sigma modulator and digital filter- Selectable 24-bit, Left-justified or IS Serial ing/decimation. Sampled data is transmitted by the Audio Interface Formats serial audio interface at rates from 8 kHz to 192 kHz in either Slave or Master Mode.
