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-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) grade. The CDB5345 Cus-
tomer Demonstration board is also available for device
evaluation and implementation suggestions. Please re-
fer to “Ordering Information” on page 42 for complete
details.
