  • OPA847: opa847

    Part Number: OPA847 hello everyone, i designed a transimpedance amplifier circuit using opa847, with the cd=30pf， rf=1k when the cf=0pf, the fft of the output noise seems to have a high q, while i tuning cf to 0.3pf， the q seems to decrease and the c…

  • RE: OPA847: how can i connect the tia output of opa847 to next stage op?

    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…
