Note 8: Typicals are at T
Note 9: Limits are guaranteed to National's AOQL (Average Outgoing Quality Level).
Note 10: TUE (Total Unadjusted Error) includes Offset, Gain and Linearity errors of the ADC.
Note 11: Total Monitoring Cycle Time includes temperature conversion, 7 analog input voltage conversions and 2 tachometer readings. Each input voltage
conversion takes 100 ms typical and 112 ms maximum. 8-plus sign Temperature resolution takes 100 ms typical and 112 ms maximum, while 11-bit plus sign
takes 800 ms typical and 900 ms maximum. Fan tachometer readings take 20 ms typical, at 4400 rpm, and 200 ms max.
Note 12: The total fan count is based on 2 pulses per revolution of the fan tachometer output.
Note 13: Timing specifications are tested at the Serial Bus Input logic levels, V
SCL and SDA edge rates are similar.
