On recovery from Power-down, the serial data output
DATAO is held LOW until valid data is available from the
decimation filter. This time tracks with the sampling
frequency:
Power-down mode/input voltage control
The PWON pin can control the power saving together with
the optional gain switch for 2 or 1 V (RMS) input.
The UDA1361TS supports 2 V (RMS) input using a series
resistor of 12 k . For the definition of the pin settings for
1 or 2 V (RMS) mode, it is assumed that this resistor is
present as a default component.
