Part Number:OPA4379
Dear TI:
In BLE thermometer project using OPA4379 has damage phenomenon. By the screenshots shown below:
The OPA power supply voltage(AVCC) is controlled by CC2541 P1_0 . When AVCC is low and battery is full, OPA input always connect on the resistive divider network .
Please help analyze , the input voltage is higher than the supply voltage might damage the OPA ? Or is there any other possibility of damage ? Many thanks~
