When debugging AMC1200TDWVRQ1, it was found that the temperature drift was very large, and the consistency between chip and chip was also poor.
After storing the PCB into the shell and placing it in a high temperature box (55 or -30 C) for 30 minutes, the output of the chip will be greatly offset, and the threshold will shift greatly at high temperature and the threshold will shift downward at low temperature. Some deviations of about 30V at 55 and -30 C
Do you help to find out where my parameters are not reasonable
Or is there a small chip with good linearity and temperature drift? Thank you.
