CS4327

Low Cost, 20-Bit, Stereo, Audio D/A Converter

Features

Description

The CS4327 is a complete stereo digital-to-analog out-

put system. In addition to the traditional D/A function, the

CS4327 includes a digital interpolation filter followed by

an 128X oversampled delta-sigma modulator. The mod-

ulator output controls the reference voltage input to an

ultra-linear analog low-pass filter. This architecture al-

lows for infinite adjustment of sample rate between 1 and

50 kHz while maintaining linear phase response simply

by changing the master clock frequency.

20-Bit Conversion

108 dB Signal-to-Noise-Ratio (EIAJ)

100 dB Dynamic Range

Single-Ended Outputs

Complete Stereo DAC System

- 128X Interpolation Filter

- Delta-Sigma DAC

- Analog Post Filter

The CS4327 also includes an extremely flexible serial

port utilizing mode select pins to support multiple inter-

face formats.

Low Clock Jitter Sensitivity

Filtered Line-Level Outputs

- Linear Phase Filtering

The master clock can be either 256, 384, or 512 times

the input sample rate, supporting various audio

environments.

- Zero Phase Error Between Channels

Digital De-emphasis for 32 kHz, 44.1 kHz &

48 kHz
