DESCRIPTION

GENERAL DESCRIPTION
The UDA1330ATS is a single-chip stereo DAC employing
bitstream conversion techniques.
The UDA1330ATS supports the I
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 UDA1330ATS can be used in two modes: L3 mode or
the static pin mode.
In the L3 mode, all digital sound processing features must
be controlled via the L3 interface, including the selection of
the system clock setting.
In the two static modes, the UDA1330ATS can be
operated in the 256f
Muting, de-emphasis for 44.1 kHz and four digital input
formats (I
be selected via static pins. The L3 interface cannot be
used in this application mode, so volume control is not
available in this mode.
