1.3
The sound processing features of the UDA1345TS can
only be used in L3 microcontroller mode:
• Digital dB-linear volume control (low microcontroller
• Digital de-emphasis for 32, 44.1 and 48 kHz
• Soft mute via cosine roll-off (in 1024 samples).
Note: in contrast to the UDA1344TS, the UDA1345TS
does not have bass-boost and treble.

The UDA1345TS is a single-chip stereo Analog-to-Digital
Converter (ADC) and Digital-to-Analog Converter (DAC)
with signal processing features employing bitstream
conversion techniques. The low power consumption and
low voltage requirements make the device eminently
suitable for use in low-voltage low-power portable digital
audio equipment which incorporates recording and
playback functions.
The UDA1345TS supports the I
word lengths of up to 24 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 UDA1345TS also supports three combined data
formats with MSB justified data output and LSB 16, 18
and 20 bits data input.
The UDA1345TS can be used either with static pin control
or under L3 microcontroller interface. In L3 mode the
UDA1345TS has basic sound features in playback mode
such as de-emphasis, volume control and soft mute.
