NJU8402
PRELIMINARY
DIGITAL TO ANALOG CONVERTER
FOR STEREO AUDIO
s 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 I2S serial data format and LSB justified.
Therefore, the NJU8402 is suitable for CD, MD, DAT
and other digital audio applications.
