1. All voltages are measured with respect to GND, unless otherwise specified.
2. Typicals are at T
3. TUE (Total Unadjusted Error) includes Offset, Gain, and Linearity errors of the ADC, multiplexer, and on−chip input attenuators, including
4. Total monitoring cycle time is nominally m × 755 ms + n × 33244 ms, where m is the number of channels configured as analog inputs, plus 2
5. The total fan count is based on two pulses per revolution of the fan tachometer output.
6. Open−drain digital outputs may have an external pullup resistor connected to a voltage lower or higher than V
7. All logic inputs except ADD are tolerant of 5.0 V logic levels, even if V
8. Timing specifications are tested at logic levels of V
