High-Performance 24-Bit 192 kHz D/A Converter Features
Built-in Electronic Volume Control and DSD Support
.DataSOverview
wwThe LC708728V is a high-performance stereo D/A
w converter developed for high-end audio applications such
Features
• Stereo D/A converter that supports both 24-bit PCM and
1-bit DSD
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
m192 kHz. It can also be used in a DSD (Direct Stream
oDigital) compatible mode by supplying a 64-bit stream for
.ceach input channel.
This IC is formed from serial interface port, digital
interpolation filter, multi-bit ∑∆ converter, and stereo D/A
Uconverter functions. It includes muting and attenuator
circuits that can be controlled individually for each
t4channel.
The operating mode can be selected to be either software
econtrol mode or hardware control mode. In software
econtrol mode, the IC can be controlled by a
microcontroller over a 2-wire or 3-wire serial port. In this
hmode, a wide range of functions, including muting,
attenuation, and phase inversion can be controlled.
SDSD mode can only be used in hardware control mode.
taThis IC is optimal for use as an interface for AC-3, DTS,
and MPEG audio decoders for surround control, and for
ause in DVD players that support DVD-A.
