D/A Converter for Digital Audio

OVERVIEW

The SM5865BM is a 24-bit input D/A converter for

digital audio equipment. It comprises newly devel-

oped DEM (dynamic element matching) circuits,

3rd-order

危鈭?/div>

noise shaper and 23-level quantizer to

control wide-band residual quantization noise in the

signal band, making it ideal for application with

high-frequency sampling formats. Also, the order of

the required 铿乶al-stage analog lowpass 铿乴ter can be

reduced, compared to 铿乴ters for available devices,

enhancing output tone quality. The output stage

employs complementary outputs for high-accuracy

analog signals, with appropriate lowpass 铿乴tering of

the output signal.

A single SM5865BM IC can be used in combination

with an 8-times oversampling digital 铿乴ter for con-

version for a single audio channel.
