NOTES:
1. V
DD
(rising edge) voltage below which the ADC is disabled.
2. V
DD
(falling edge) voltage below which the logic is reset.
3. Address is read a power up and at start of conversion for all conversions except the fastest rate.
4. Due to the bias current, any pull-up/down resistors should be
≤
2kΩ.
