Part Number: OPA656 Other Parts Discussed in Thread: OPA657 , Hi
I'm testing a tanspidence circuit and find that the temperature at the case of OPA657/OPA656 rises to around 51~52C.
The ambient temperature is around 25C.
The OPAmp is supplied by ±4…
Hi Matthew,
Matthew Dion said: Looking at the specs of the low-leakage steering diodes, I believe adding them to the input will introduce unacceptable leakage into my circuit. So I will attempt to add a bidirectional Zener TVS diode to clamp the inputs…

Part Number: OPA656 Other Parts Discussed in Thread: OPA356 , , OPA357 Hi,
I am trying to build Peak Detector for 1V 2MHz signal using OPA656. I want to use +-5V supply instead of +-2.5V. Same circuit works with OPA356 but not with OPA656.
Why does OPA656…
Hi Andrew, this part has a decompensated version, the OPA657. You can externally compensate the OPA657 with either a differential input resistor or a feedback capacitor to get nearly identical performance. Alternatively, the LMH6629 and OPA855 are also…

Part Number: OPA656 Hi,
Have the below circuit with OPA656, without or with input, have the below interesting issue.

Part Number: OPA656 Other Parts Discussed in Thread: OPA657 , OPA695 , OPA830 Hiii
My photodiode current is very less (5Micro ampere to 10 micro ampere). So the standard transimpedance amplifier can't give the optimum performance since signal is mixing…
