  • OPA354: LTspice Stability Simulation of OPA354 – Unexpected AOL Results

    Part Number: OPA354 Tool/software: Hello, I am trying to run a stability simulation in LTspice for the OPA354 differential amplifier, following the method shown in TI’s training presentations. The goal is to extract the phase margin by plotting Aol…

  • RE: OPA354: OPA354

    Hi Ignacio, you are right, I got confused between the SiPM and the TIA input. In the configuration I need to implement, the SiPM sources current on the anode, while the TIA input sinks current; therefore, the IDC_EN pin should be set high. This is very…

    Part Number: OPA354 Hi, Could you tell me the test circuit and conditions when you get the graph below? I want to make use of the circuit and conditions that can realize the characteristics of this graph in the design. And I want to test at TINATI. …

  • WEBENCH® Tools/OPA354: bandpass filter design tools

    TI Thinks Resolved
    Part Number: OPA354 Tool/software: WEBENCH® Design Tools Hi, I want to find a tool to help me design the bandpass filter, but I can't find the access. Both the WEBENCH and Filter pro. So, can you give me the access? Thanks!

  • RE: OPA354: ( Non ) Inverting attenuator is stable?

    Hey Hasan, The is a typical test circuit that misses an important issue. Your sim shows 60deg phase margin, but if you do this correctly (where the device output impedance see the feedback path and partcularly the input C added externally here, it goes…
