Overview
The LC708728V is a high-performance stereo D/A
converter developed for high-end audio applications such
as DVD systems, home theater systems, and digital TV
sets. It supports 16 to 32-bit word length PCM data as its
digital input format, and supports sampling rates up to
192 kHz. It can also be used in a DSD (Direct Stream
Digital) compatible mode by supplying a 64-bit stream for
each input channel.
This IC is formed from serial interface port, digital
interpolation filter, multi-bit
∑ converter, and stereo D/A
converter functions. It includes muting and attenuator
circuits that can be controlled individually for each
channel.
The operating mode can be selected to be either software
control mode or hardware control mode. In software
control mode, the IC can be controlled by a
microcontroller over a 2-wire or 3-wire serial port. In this
mode, a wide range of functions, including muting,
attenuation, and phase inversion can be controlled.
DSD mode can only be used in hardware control mode.
This IC is optimal for use as an interface for AC-3, DTS,
and MPEG audio decoders for surround control, and for
use in DVD players that support DVD-A.
