But FW can't capture stable value, use the scope capture the lmt84(temperature sensor) output signal is pull down in about 100KHZ. If I disconnet the output pin to P3.7, the lmt84 output signal is stable.

Hi Kent,

See the schematic below. Keep the opamp in follower mode in configuration. Make sure you call Opamp start in the firmware.
