L3 mode
The UDA1344TS is set to the L3 mode by setting both
pins MC1 and MC2 to LOW level.
The static pins in this mode are used for:
• ADC output overload detection
• L3 interface signal input
• ADC input voltage selection.
The controllable features via the L3 interface and the
definition of the control registers are given in
Section “L3 interface”.
P
The pinning definition in the L3 mode is given in Table 11.

ADC
In practice the output is used to indicate whenever the
output data, in either the left or right channel, is greater
than −1 dB (actual figure is −1.16 dB) of the maximum
possible digital swing. When this condition is detected
pin MP1 is forced to HIGH level for at least 512f
(11.6 ms at f
infringement.
ADC
In the L3 mode pin MP5 is used to select 0 or 6 dB gain.
