(1)

The SMBus timeout in the AMC80 resets the interface anytime SCL or SDA is low for over 28 ms.

(2)

LSB means least significant bit.

(3)

Total unadjusted error contains offset, gain, and linearity errors of the ADC.

(4)

Total conversion time contains the temperature conversion, the seven analog input voltage conversions, and the two tachometer

readings.
