An x indicates that the diode exists.
Note 9: Typicals are at T
Note 10: Limits are guaranteed to National’s AOQL (Average Outgoing Quality Level).
Note 11: The Temperature Error specification does not include an additional error of
Note 12: The Temperature Error will vary less than
Note 13: TUE (Total Unadjusted Error) includes Offset, Gain and Linearity errors of the ADC.
Note 14: Total Monitoring Cycle Time includes all diode checks, temperature conversions and analog input voltage conversions. Fan tachometer readings are
determined separately and do not affect the completion of the monitoring cycle.
Note 15: This is the lowest DAC code guaranteed to give a non-zero DAC output.
Note 16: The total fan count is based on 2 pulses per revolution of the fan tachometer output.
Note 17: Timing specifications are tested at the specified logic levels, V
