8.3.8 Packages with an Exposed Thermal Pad

The OPAx310 family is available in packages such as the WQFN-16 (RTE), which feature an exposed thermal

pad. Inside the package, the die is attached to this thermal pad using an electrically conductive compound. For

this reason, when using a package with an exposed thermal pad, the thermal pad must be connected to (V–).

Attaching the thermal pad to a potential other then (V–) is not allowed, and the performance of the device is not

assured when doing so.

8.4 Device Functional Modes

The OPAx310 devices have a single functional mode. These devices are powered on as long as the power-

supply voltage is between 1.5 V (±0.75 V) and 5.5 V (±2.75 V).

The OPAx310S devices feature a shutdown pin, which can be used to place the op amp into a low-power mode.

See Shutdown Function for more information.
