The CS5345 performs stereo analog-to-digi- tal (A/D) conversion of up to 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 avail- able 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 filter- ing/decimation. Sampled data is transmitted by the serial audio interface at rates from 4 kHz to 192 kHz in either Slave or Master Mode. Integrated level translators allow easy interfacing be- tween the CS5345 and other devices operating over a wide range of logic levels. The CS5345 is available in a 48-pin LQFP package in Commercial (-10° to +70° C) and Automotive (-40° to +105° C) grade. The CDB5345 Customer Demonstra- tion board is also available for device evaluation and implementation suggestions.
