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.
