CS5345

105 dB, 24-Bit, 192 kHz Stereo Audio ADC

A/D Features

General Description

Multi-bit Delta Sigma modulator

105 dB dynamic range

-95 dB THD+N

Stereo 6:1 Input Multiplexer

Programmable Gain Amplifier (PGA)

– +/- 12 dB gain, 0.5 dB step size

– Zero crossing, click-free transitions

Stereo microphone inputs

– +32 dB gain stage

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.

– 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

Integrated level translators allow easy interfacing be-

tween the CS5345 and other devices operating over a

wide range of logic levels.

High pass filter or DC offset calibration

System Features

Power down mode

+3.3 V to +5 V analog power supply, nominal

+3.3 V to +5 V digital power supply, nominal

Direct interface with 1.8 V to 5 V logic levels

Pin-compatible with CS4245
