I am searching one kind of opamp to work on +-18V. ADA4000-4 may be the choice as the datasheet said that "±4 V to ±18 V operation". However, I also found in the datasheet that the maximum supply voltage is "±18 V".
I just read your answer, I will try to check on devices what happens taking into account your question.
I also have additional clues for this issue. ADA4000 datasheet precises that without voltage supplies (power voltages), input current…
I tried replacing a TL082 which was working fine in the attached circuit with ADA4000.
I am very unhappy with the stability fo ADA4000. The input is from an DAC (100KHz) and the output is at output pin of Opamp.
What could be a direct replacement for…
I think you might be stuck. The precsion bipolar op amps usually have diodes between the inputs to protect the diff pair so you don't zener the EB junction. You might look at some of the JFET op amps, such as the ADA4000-4 or the AD8513, but…
How is your circuit coming along so far? I think it would be easy for you to just maintain your original schematic and replace the AD8606 parts with any one of these: ADA4610-2 (Dual), ADA4610-4(Quad) and ADA4000-4(Quad). These parts really…
Recommended alternative parts for AD711 from the product page in this link are:
You can refer to this link regarding maximum safe input overload condition of ADA4000.
Thanks for the clarification. This question came from a customer of mine. The application is biologic spectral testing. Thanks for the heads up on the ADA4000-1, I will pass this info along to the customer.
