6.1.1 Operating Voltage

The INA132 operates from single (2.7V to 36V) or dual (±1.35V to ±18V) supplies with excellent performance. Specifications are production tested with +5V and ±15V supplies. Most behavior remains unchanged throughout the full operating voltage range. Parameters that vary significantly with operating voltage are shown in the Typical Characteristics.

The internal op amp in the INA132 is a single-supply design. This design allows linear operation with the op-amp common-mode voltage equal to, or slightly below V– (or single supply ground). Although input voltages on pins 2 and 3 that are less than the negative supply voltage do not damage the device, operation in this region is not recommended. Transient conditions at the inverting input terminal less than the negative supply can cause a positive feedback condition that can lock the INA132 output to the negative rail.

The INA132 can accurately measure differential signals that are greater than the positive power supply. The linear common-mode range extends to nearly twice the positive power supply voltage—see typical characteristics curve, Common-Mode Range vs Output Voltage.
