2. Stand-alone mode
The AC cjaracteristics values of stand-alone mode are proportional to the period of the
sampling frequency (fsamp).
DVDD=DVDD’=AVDD=2.7 to 3.6 V, DGND=AGND=0 V, Ta= –40 to +85°C
When fsamp=8 kHz

Note: 1. When the PDMD pin is "L", the oscillation stable time is added to tST. The oscillation
stable time is several tens of milliseconds for crystal oscillators and is several
hundreds of microseconds for ceramic oscillators.
