OPA2192-Q1: P2P but higher voltage rating OPA

Hi Roy,

these are the OPAmps which can handle more than 36V supply voltage:

Hi Roy,

We have a few high voltage power amps that you may look at: https://www.ti.com/amplifier-circuit/op-amps/products.html#p1261max=45;180 

Hi All,

Thanks for suggestion. But we need dual power input that could support V+=36V and V-=-.9V.

it looks that our solution couldn't meet the requirement.

Hi Roy,

V-=-.9V.

or this

V-=-9V

If the first is true, then just decrease the positive supply voltage a bit and use input voltage dividers, if necessary.

Hi Roy,

We do not have an exact high-voltage P2P replacement op amp that can drop into the OPA2192-Q1 board position. Links to high-voltage op amp alternatives have been suggested by Kai and Tamara, but these op amps will differ in their electrical performances from the OPA2192-Q1. Additionally, most of the high-voltage op amps have a enable/shut down function which require their EDCOM pin (pin 8) and a bottom side power pad be connected to certain voltages. Therefore, these high-voltage op amps would likely require PC board changes. And there is the Q1 requirement. When I check TI.com I don't see any of these high-voltage op amps available with the -Q1 extension. 

It doesn't appear that we have a solution that readily works.
