TLV9352: If the input voltage is not constant, is there a possibility of damage?

Part Number: TLV9352

Hi,

I am using your product "TLV9352" for the following application.

Purpose：voltage follower

Supply voltage：+12V, GND

Under the above conditions, is there a possibility of damage if the input voltage is indeterminate?

    What exactly do you mean with "indeterminate"?

    A changing input voltage is no problem. (And input voltages near V+ are no problem either.) But the inputs should always be driven to some voltage, i.e., the inputs should not float. Otherwise, extreme input voltages could make the amplifier go into a saturated state (see section 7.3.8 of the datasheet).

    If it is possible that there is no signal source, you can add a weak voltage divider (e.g., 1 MΩ + 1 MΩ) to ensure that the input voltage is always biased somewhere.
