6.4 Device Functional Modes

The INA122 can be operated on a single power supply as low as +2.2V (or a total of +2.2V on dual supplies).

Performance remains excellent throughout the power supply range up to +36V (or ±18V). Most parameters

vary only slightly throughout the full supply voltage range. See the typical performance curves in Typical

Characteristics section.

Operation at very low supply voltage requires careful attention to maintain the linear operating condition with the

input common-mode voltage range, as explained in the Input Common-Mode Range section.
