7.3.2 Output Current Limit

The output current of the OPAx145 is limited by internal circuitry to +20 mA (sinking) and –20 mA (sourcing) to protect the device if the output is accidentally shorted. This short-circuit current depends on temperature, as shown in GUID-5BEFE92A-0D9A-4253-B1A4-27BE8C08CE4F.html#SBOS427_ISCOVERTEMP.
