GENERAL DESCRIPTION
The UDA1320ATS/N2 is a single-chip non inverting stereo
DAC employing bitstream conversion techniques. The low
power consumption and low voltage requirements make
the device eminently suitable for use in digital audio
equipment which incorporates playback functions.
The UDA1320ATS/N2 supports the I
2
S-bus data format
with word lengths of up to 20 bits, the MSB-justified data
format with word lengths of up to 20 bits and the
LSB-justified serial data format with word lengths of 16,
18 and 20 bits.
The UDA1320ATS/N2 can be used in two modes, either
L3-mode or static pin mode.
In the L3-mode, all digital sound processing features must
becontrolledviatheL3 interface,includingtheselectionof
the system clock setting.
In the two static-modes, the UDA1320ATS/N2 can be
operated in the 256f
s
and 384f
s
system clock mode. The
mute,de-emphasisfor44.1 kHzand4 digitalinputformats
(I
2
S and 16, 18, 20 bits LSB formats) can be selected via
static pins. The L3 interface cannot be used in this
application mode, also, volume control is not available in
this mode.
