D/A Converter

OVERVIEW

The SM5865AM is a 24-bit input D/A converter for

high-quality digital audio equipment. It comprises

newly developed DEM (dynamic element matching)

circuits, 3rd-order

Σ∆ noise shaper and 23-level

quantizer to control wide-band residual quantization

noise in the signal band, making it ideal for applica-

tion with high-frequency sampling formats. Also, the

order of the required ﬁnal-stage analog lowpass ﬁlter

can be reduced, compared to ﬁlters for available

devices, enhancing output tone quality. The output

stage employs complementary outputs for high-accu-

racy analog signals, with appropriate lowpass ﬁlter-

ing of the output signal.

A single SM5865AM IC can be used in combination

with an 8-times oversampling digital ﬁlter for con-

version for a single audio channel.
