The ADC has a built-in low pass filter for noise rejection that is programmable for a 10 to 1900
Hz cutoff. The filter has notches at multiples of the cutoff frequency.
The ADC provides for up to 65.535 seconds of sensor warm-up delay before making its first
measurement. If the specified warm-up delay is less than 3 sampling periods, the delay before
the first reading is taken will be 3 sampling periods. This should be taken into account when
computing the warm-up delay.
Accuracy
The ADC will self calibrate to its internal reference whenever the calibrate command is received.
The reference, while very stable, is accurate to
1mV. This error is measured during factory test
and is written into the ADC ROM. A read Vref error command can be used to read this error and
use it to obtain 0.0015% error (at 25
C). Another set of coefficients can be read to calibrate
readings when the ADC gain is set to 16.
