Hello Nomura-san,
Daisuke Nomura said: Customer think that the allowable voltage range of the OPA462 is not sufficient to achieve a 300V output, is their understanding correct?
The understanding is correct. OPA462 on its whole is unable to support 300V…
Part Number: OPA462 Other Parts Discussed in Thread: OPA810 Tool/software: Hello,
I've designed a small high voltage bridge based on the LTC6090, somehow OK...and wanted to try out the OPA462.
I've swapped the ICs, but it is not working as expected…
Hi Hari,
Both the OPA462 application note and the THS3491 reference design show the maximum extendable range of the power supply using the bootstrapping technique. Notice that both designs use the maximum single power supply voltage for the bootstrapping…
Part Number: OPA462 Other Parts Discussed in Thread: DRV2700 Hi,
I am using OPA462 to drive a high voltage piezo load about 2uF. The supply voltage is set initally 0(V-) and 150V(V+). And after tested on demo a board, I have met a few issues.
1. The input…
Part Number: OPA462
Hi,
I am trying to run a simulation which is of a circuit found in

The circuit is found in figure A-3
However when…
Part Number: OPA462 Other Parts Discussed in Thread: OPA365 , , OPA593 , OPA192 , OPA455 HI bro
in my case，the OPA is very hot，the System can run only few minites and the the OPA will broken。so can you tell me How to Calculate the the Power Consumption of…
Part Number: OPA462 Hi team,
According to the datasheet, it seems that the output impedance just increases to about 160kOhm while the device is disabled.
But are there any changes else while the device is disabled?

Hi Robert,
Thank you for getting back to us regarding your findings about the OPA462 circuit. I'm glad you were able to determine that the lack of a dc path for the input is the cause of the problem.
If you require any additional assistance going forward…
Part Number: OPA462 Other Parts Discussed in Thread: OPA455 , OPA454 , OPA593 Hello,
I have been trying to find a replacement for the ADA4700-1 (first amplifier in the picture below) and the OPA462 seemed like a good fit as it shared the package, the high…
Part Number: OPA462 Hello
We provide a differential voltage power supply, powering the OPA462
I noticed, on start-up, the negative voltage V- arrives before the positive V+.
On the positive power supply we have a little undershoot of -1.4V, while the…
