Hi team.

I'd like to know about LMV118.

When there is no power supply, what is the output?

Is it Hi-Z ?

If your answer is without Hi-Z, could you introduce a device with similar performance that it has Hi-Z when there is no power?

Sincerely.

Kengo.

Kengo,

The output is HI-Z until the diodes from output to the two power rails conduct current. See data sheet sections 6.1 and 7.2. This is true of almost all op amps. Why do you need this HI-Z?

Hi Ron.

Thank you for your reply.

Where should I refer to in data sheet sections 6.1 and 7.2?

Does the output change depending on the output stage configuration when the power is off?

Almost opamp is Hi-Z as you say?

Sincerely.

Kengo.

Kengo,

6.1 , see green box

7.2, see green box

Why does it matter when the power is off? What is connected to the output?

Because of the holidays, TI E2E™ design support forum responses will be delayed from Dec. 25 through Jan. 2. Thank you for your patience.
