So there was a miswire in the negative bias to the diodes, fixed that - the response to the output of the OPA847 looks fine, not sure this is the shape you want.Those diodes divider bias networks are causing that lower frequency shift and reducing the…
Part Number: OPA847 Other Parts Discussed in Thread: OPA855 Why went I use the inventory search can I not get the OPA847 to appear, I used the high speed op amps >50MhZ, de-selected all the conditional search critera. I can't get it to come up when I…
Part Number: OPA847 Other Parts Discussed in Thread: OPA855 , OPA657 , OPA858 my bro designed a tia circuit using opa847,the pin has a cap of 25 pf ,two pin consists a parall cap of 50 pf,now i need to make the circuit have 200Mhz bandwidth,and a flat freq…
Part Number: OPA847 Other Parts Discussed in Thread: OPA657 , , OPA838 Hello Everyone? I have an oscillation issue on a photodiode trans-impedance amplifier whose simplified schematic I'm attaching in this thread. The design consists of a high gain / high…
