DIGITAL TO ANALOG CONVERTER
FOR STEREO AUDIO
I
GENERAL DESCRIPTION
The
NJU8402
is a 16-bit delta-sigma Digital-to-Analog
Converter for stereo audio. It consists of Serial Audio Data
Interface, Digital Interpolation Filter,
Σ
Modulator, SC LPF,
Buffer Amp, System Controller for status control. It
operates on single +5V power supply. Furthermore, it
accepts 16-bit input audio data length or 18-bit, and
supports I
2
S serial data format and LSB justified.
Therefore, the
NJU8402
is
suitable for CD, MD, DAT
and other digital audio applications.
