7.3.3 Reference Output

The AMC1035-Q1 offers a voltage reference output that can source or sink current to significantly reduce the gain error thermal drift in ratiometric applications as specified in the Electrical Characteristics table. The IGBT Temperature Sensing section provides an example of a ratiometric use case for the AMC1035-Q1.

The reference output can drive capacitive loads less than 1 nF. Use a series resistor to avoid oscillations and degradation of performance for capacitive loads ≥ 1 nF. Table 2 lists the recommended series resistor values for given capacitor value examples. Interpolate for capacitive loads with a value between the given examples.
