OPA2134: Disable Circuit

Part Number: OPA2134
Other Parts Discussed in Thread: TLC2274,


can you please look at the attached cirucit diagram. What you think about it.

I believe ist risky because we can have a voltage at the output while no supply voltage is present

Basically we need a programmable treshold value that has a Default value when the uC is not operating.

We also need a solution that we can adapt for a high temperature design and we did not find an amplifier with enable for this.

The circuit Shows TLC2274 but as mentioned below we want to use the OPA2134.

Best regards,
