  • Calculating External Compensation components for LMP7717 for Unity gain configuration.......!

    Other Parts Discussed in Thread: LMP7717 , OPA320 , LMP7701 , LMP7715 Hi, We are using LMP7717 as Unity gain amplifier. The datasheet says if gains<10 , op-amp should be externally compensated. But the values are mentioned based on Rf as non-zero.…

  • OPA365: I need an alterative to OPA365AIDBVT, could anyone recommend a solution?

    TI Thinks Resolved
    Part Number: OPA365 Other Parts Discussed in Thread: , LMV793 , OPA607 , LMP7717 , Also, could someone from TI provide me with an update on lead times/stocking levels at TI and distys for OPA365AIDBVT.

  • RE: OPA392: Is a spice model available for the forthcoming OPA392 part

    Normally John, in transimpedance you want a decompensated op amp to get lower noise and high gain or BW. You might look at the LMP7717 also.

  • RE: LMP7721:

    You will get more dynamic range using a decompensated device like the LMP7717, There is a section in this article on transimpedance design - no way to pursue this query without a source capacitance number. The end of this article includes tables of parts…

  • RE: OPA189: Recommended for Photodiode Transimpedance Amplifier Application

    Also Rachel, that LMP7717 is going to show up in a July article where I had built tables of decomp parts. The TINA model actually shows a true GBP of 109Mhz on that device - you would use that in Eq.1 in prior post,

  • LMH6642: Photo-Diode Current-to-Voltage Conversion

    TI Thinks Resolved
    Other Parts Discussed in Thread: LMH6642 , OPA228 , LMP7717 Hello, Referring to page 3 of this document: http://www.ti.com/lit/an/snoa423b/snoa423b.pdf Customer is looking for photodiode current-to-voltage conversion, however, he mentions that the current…
