General Description
The CS5345 integrates an analog multiplexer, program-
mable gain amplifier, and stereo audio analog-to-digital
converter. The CS5345 performs stereo analog-to-digital
(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 or microphone level inputs. The mi-
crophone 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 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.
