NOTES:
1. V
CC = 2.7 to 5.5 V at Topr = -20 to 85 °C / -40 to 85 °C, unless otherwise specified.
2. If f1 exceeds 10 MHz, divided f1 and ensure the comparator conversion operating clock frequency (φ
AD) is 10 MHz or below.
3. If AVcc is less than 4.2 V, divided f1 and ensure the comparator conversion operating clock frequency (φ
AD) is f1/2 or below.
