10 Power Supply Recommendations

The nominal performance of the INA823 is specified with a supply voltage of ±15 V and midsupply reference voltage. The device also operates using power supplies from ±1.35 V (2.7 V) to ±18 V (36 V) and non-midsupply reference voltages with excellent performance. Parameters that can vary significantly with operating voltage and reference voltage are shown in Section 7.6.

CAUTION:

Supply voltages higher than 40 V (±20 V) can permanently damage the device.
