  • RE: LMC6001: LMC6001 Input Capacitance

    HI Jacob, The LM6001 device was developed a few years ago (1995). I would need to look for this information and see if it is available.. Nevertheless, we offer the new OPA928 femtoampere-input-bias precision amplifier that is currently sampling/preview…

  • RE: LMP7721: Transimpedance amplifier - Question about layout, guard and copper pours

    Hi Alan, No problem. I am happy to support a femtoampere-level design, especially an interesting one like this! I have a few more notes on your design, see below. 1.) Now I think the capacitor pin and trace should all be inside the guard, both on the top…

    Thanks for the suggestion. When is OPA928 expected to be launched ?

  • LMP7707: The effect of the photodiode dark current and the op amp's own bias current on the op amp integration circuit

    Part Number: LMP7707 Other Parts Discussed in Thread: IVC102 , LMP7721 , OPA328 , OPA928 , OPA3S328 , OPA320 , STRIKE Hi Using your op amp LMP7707 to build an integral circuit to integrate the photodiode output current signal, PD is a photovoltaic mode zero…

  • RE: pA to nA current sensing - which amplifier product?

    Hi Raymond, Our devices are fabricated on-chip, so the electrode spacing is fixed. If we were to try the OPA928 or OPA928EVM, would we need to configure the circuit as a high or low-side measurement? We are very much interested in both the transient current…
