Description

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) conve rsion of 24-bit serial values at sa mple 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 5thorder, 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.
