CS5345  
104 dB, 24-Bit, 192 kHz Stereo Audio ADC  
A/D Features  
General Description  
 Multi-Bit Delta Sigma Modulator  
 104 dB Dynamic Range  
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.  
 -95 dB THD+N  
 Stereo 6:1 Input Multiplexer  
 Programmable Gain Amplifier (PGA)  
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.

+32 dB Gain Stage  
Low-Noise Bias Supply  
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.  
 Up to 192 kHz Sampling Rates  
 Selectable Serial Audio Interface Formats

Left-Justified up to 24-bit  
I²S up to 24-bit  
 High-Pass Filter or DC Offset Calibration  
Integrated level translators allow easy interfacing be-  
tween the CS5345 and other devices operating over a  
wide range of logic levels.  
System Features  
 Power-Down Mode  
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. Please refer to “Ordering  
Information” on page 41 for complete details.
