  • OPA855: TIA PSpice simulation issue with Opamp OPA855

    Part Number: OPA855 Tool/software: Hello TI teams, Firstly hope all is doing well. In the case of the implementation of a TIA for SiPM sensor application I tried to simulate a dummy TIA circuit using OPA855 but the output gain is unexpected (very…

  • OPA855-Q1: OPA855-Q1

    Part Number: OPA855-Q1 Other Parts Discussed in Thread: OPA855 We are developing Lidar by applying OPA855-Q1. OPA855-Q1 product bandwidth is 8GHz. The PD Bandwidth we are applying is 2GHz. We use the product at 100MHz. Is it possible for the product to…

  • OPA855: OPA855: When the OPA855 is designed for TIA, what is the maximum closed-loop bandwidth it can achieve?

    TI Thinks Resolved
    Part Number: OPA855 Tool/software: Hello, everyone. I am currently going to build a TIA circuit using OPA855, I want to make the TIA bandwidth up to 1.7GHz, and I am designing it based on the values from the TIA calculator. But the bandwidth of the…
