Under static pin control the options are 256f
With pin MP3 (pin 14) the mode can be set as is given in
Table 8.

7.11.3
Under static pin control via MP2 de-emphasis and mute
can be selected for the playback path. The definition of the
MP2 pin is given in Table 9.

7.11.4
The data input/output formats supported under static pin
control are as follows:
• I
• MSB-justified serial format with data word length of up to
• Two combined data formats with MSB data output and
The data formats can be selected using pins MP1 (pin 9)
and MP5 (pin 20) as given in Table 10.
Table 10 Data format settings under static pin control
The formats are illustrated in Fig.3. Left and right data
channel words are time multiplexed.

The UDA1345TS supports a 2 V (RMS) input using a
series resistor as described in Section 7.2.
In static pin mode the 3-level pin MP4 (pin 15) is used to
select 0 or 6 dB gain mode. When MP4 is set LOW the
ADC is powered-down. When MP4 is set to half the power
supply voltage, then 6 dB gain is selected, and when MP4
is set HIGH then 0 dB gain is selected.
