Other Parts Discussed in Thread: TLV4120 Hi,
I have a circuit that was designed by another engineer. I would like to simulate specific parts in the circuit in order to test their behavior and to improve the design. One important part is missing a spice…
Frank,
No the op amp output is not in high impedance if the power supplies are powered down.
This is because there are parasitic diodes across the output transistors. These diodes will turn on when a signal is applied to the output of the op amp…
The OPA145 also looks like a good choice, this file has not been recently updated so the OPA196 is not in yet, and the pricing is out of date.

to User473,
I searched all the op amp portfolio with the parametric search (precision, general purpose, and high-speed). There are 6 options with temperatures of 150C and above (see attached). The best match is the OPA211-HT (210C max). This is the…
