CS5346

103 dB, 192 kHz, Stereo Audio ADC with 6:1 Input Mux

ADC Features

General Description

Multi-bit Delta Sigma Modulator

103 dB Dynamic Range

The CS5346 integrates an analog multiplexer, program-

mable gain amplifier, and stereo audio analog-to-digital

converter. The CS5346 performs stereo analog-to-digi-

tal (A/D) conversion of 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.

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 8 kHz to 192 kHz in

either Slave or Master Mode.

Up to 192 kHz Sampling Rates

Selectable 24-bit, Left-justified or I²S Serial

Audio Interface Formats

System Features

Integrated level translators allow easy interfacing be-

tween the CS5346 and other devices operating over a

wide range of logic levels.

+5 V Analog Power Supply, Nominal

+3.3 V Digital Power Supply, Nominal

Direct Interface with 3.3 V to 5 V Logic Levels

The CS5346 is available in a 48-pin LQFP package in

Commercial (-40° to +85° C) and Automotive (-40° to

+105° C) grades. The CDB5346 Customer Demonstra-

tion board is also available for device evaluation and

implementation suggestions. Please refer to “Ordering

Information” on page 40 for complete details.
