Specifications subject to change without notice.
All voltages are measured with respect to GND, unless otherwise specified.
Typicals are at T
TUE (Total Unadjusted Error) includes Offset, Gain, and Linearity errors of the ADC, multiplexer, and on-chip input attenuators, including an external series input
Total monitoring cycle time is nominally 114.4 ms. Monitoring Cycle consists of 6 Voltage + 1 Internal Temperature + 1 External Temperature readings.
ADD is a three-state input that may be pulled high, low, or left open-circuit.
Timing specifications are tested at logic levels of V
protection resistor value between zero and 1 kΩ.
