1. All voltages are measured with respect to GND, unless otherwise specified.
2. Typicals are at T
3. Timing specifications are tested at logic levels of V
4. Total unadjusted error (TUE) includes offset, gain, and linearity errors of the ADC, multiplexer, and on−chip input attenuators. V
5. Total analog monitoring cycle time is nominally 273 ms, made up of 18 ms × 11.38 ms measurements on analog input and internal temperature
6. The total fan count is based on two pulses per revolution of the fan tachometer output. The total fan monitoring time depends on the number
7. ADD is a three−state input that may be pulled high, low, or left open circuit.
8. Logic inputs accept input high voltages up to 5.0 V even when device is operating at supply voltages below 5.0 V.
9. Endurance is qualified to 100,000 cycles as per JEDEC Std. 22 method A117, and measured at −40°C, +25°C, and +85°C. Typical endurance
10. Retention lifetime equivalent at junction temperature (T
