OPA656: Shaping Amp for OPA656

Nadeera Hemamali
Prodigy 10 points
Part Number: OPA656

I am designing gamma  radiation  scintillator detector . I will use OPA656 as the Charge sensitive pre-amp- Can anybody suggest me a Shaping amplifier that are compatible with OPA656. My circuit is as shown below.

Sensor---> OPA656---> Shaping amp---->ADC---etc

Thanks in advance

    Suggestions for effective circuit help requests – item 3 is most pertinent here. 

    1. Where your question has a specific circuit/device involve, be sure to show the full circuit and more preferably a TINA schematic link. Debug usually involves circling the device pins looking both directions for interactions. What is driving your input – what is your load?
    2. “It doesn’t work” leaves a lot to be desired. Be as specific as possible where your current implementation is falling short of expectations.
    3. Eventually, any design has some target performance metrics. Detailing those will go a long way towards reaching an effective end solution. This might require changing device solutions.
