When debugging, AMC1200TDWVRQ1 found that its temperature drift is very large, and the chip and chip consistency is also very poor; after the board is placed in the housing and placed in a high temperature box (55 ° C or -30 ° C) for 30 minutes, the chip output A large offset occurs, the threshold shifts to a large value at high temperatures, and the threshold shifts downward at low temperatures. At 55 and -30 °C, there will be a deviation of about 30V. Help me check where the parameter settings are unreasonable, or if there is a chip with small temperature drift and good linearity, thank you
