Figure 8-1 shows the basic connections of the INA190-Q1. Place the device as close as possible to the current sense resistor and connect the input pins (IN+ and IN–) to the current sense resistor through kelvin connections.If present, the ENABLE pin must be controlled externally or connected to VS if not used.

NOTE: To help eliminate ground offset errors between the device and the analog-to-digital converter (ADC), connect the REF pin to the ADC reference input. When driving SAR ADCs, filter or buffer the output of the INA190-Q1 before connecting directly to the ADC.
