SM5865AM
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.
