6.4 Device Functional Modes

The OPAx991-Q1 has a single functional mode and is operational when the power-supply voltage is greater than 2.7 V (±1.35 V). The maximum power supply voltage for the OPAx991-Q1 is 40 V (±20 V).

The OPAx991S-Q1 devices feature a shutdown pin, which can be used to place the op amp into a low-power mode. See Shutdown section for more information.
