9 Power Supply Recommendations

The INA165x-Q1 operate from ±2.25-V to ±12-V supplies while maintaining excellent performance. However, some applications do not require equal positive and negative output voltage swing. With the INA165x-Q1, power-supply voltages do not need to be equal. For example, the positive supply can be set to 19 V with the negative supply at –5 V.
