We have to re-calirate an Sensoramplifier once a day, therefore we want to use the DAC7571 to create an analog "referenz" signal .
Test-Spezification:
-> 12-Bit DAC7571 at exact 3,0000V and 25,00°C,
-> always use the same DAC, on the same PCB.
Assumption:
-> Day1: with DAC-Code 2048 we measure f.e. 1,49950V (DAC Output),
Question:
-> can we expect each day 1,49950V with code 2048
or each time another value somwhere between (+/-1-LSB) 1,5V +/- 0,732mV?
