Part Number: OP07C


Tool/software:

Dears,
As the OP07C have wafer PCN,customer received products that label show CSO is RFB,then find the original design can not work,pls kindly help to suggest the reference design for RFB OP07C with Gain 10MHz.
Attachfile show the schematic.
Thanks

    Hi Li Ning,

    OP07C has GBW at approx. 600kHz. Could you explain what is 10MHz requirements?

    If I extract the R figures correctly, it should look the following simulation. This is a difference amplifier and input impedance should be balanced. On the non-inverting side, it is missing 15kohm. I inserted 10nF to limit the BW of the op amp, since this is likely current sensing circuit. My guess 1.1kHz should be adequate for the application. Please let me know if it is not, and I can revise the circuit.
