: Peak to peak amplitude during capacitance measurement
4. Below 0°C, a negative slope on Vcc will stop the oscillator during a time which may be as long as 1 second. This is not
dependent on slope and occurs with a slew rate as low as 2V/sec.
5. Some chip versions do not support “Trickle Charger” and “Switchover” features.
