8.4.1 Adjusting the Output Midpoint With the Reference Pins
Figure 33 shows a test circuit for reference-divider accuracy. The INA253 output is configurable to allow for unidirectional or bidirectional operation.w
CAUTION
Do not connect the REF1 pin or the REF2 pin to any voltage source lower than GND or higher than VS.
The output voltage is set by applying a voltage or voltages to the reference voltage inputs, REF1 and REF2. The reference inputs are connected to an internal gain network. There is no operational difference between the two reference pins.
