2. Relative accuracy is the deviation of the analog value at any code from its theoretical value after the gain error
and offset error have been nulled.
3. Offset nulled.
4. Ground on channel; sinewave applied to all off channels.
5. Conversion time is defined as the number of clock cycles multiplied by the clock period; clock has 50% duty
cycle.
6. The absolute voltage range for the analog inputs (CH0:CH7, and COM) is from GND to V
DD1
.
7. External load should not change during conversion for specified accuracy. Guaranteed specification of 4mV/mA
is a result of production test limitations.
8. AS1530/AS1531 performance is limited by the device noise floor, typically 300μVp-p.
