9.2.1.2.1 Operating Voltage

The INA592 operates from single (4.5 V to 36 V) or dual (±2.25 V to ±18 V) supplies with excellent performance. Specifications are production tested with 5-V and ±15-V supplies. Most behavior remains unchanged throughout the full operating voltage range. Parameters that vary significantly with operating voltage are shown in the Section 7.7. The internal op amp in the INA592 is a single-supply design. This design allows linear operation with the op amp common-mode voltage equal to, or slightly less than V– (or single-supply ground). Although input voltages on pins 2 and 3 that are bless 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 could lock the device output to the negative rail.

The INA592 can accurately measure differential signals that are greater than the positive power supply. For example in G = ½, the linear common-mode range extends to nearly three times the positive power-supply voltage; see the Typical Characteristics as well as Section 9.2.1.2.3.
