  • OPA892: Input voltage swinging problem

    Part Number: OPA892 Tool/software: Hello, I need to use the OPA 892D for building an amplifier circuit. My questions are listed below: 1. The datasheet does not provide sufficient information regarding how to determine the resistance value for input pin1…

  • OPA892: Issues with AC Coupled TIA Circuit Design

    Part Number: OPA892 Tool/software: Hello, I am currently designing an AC-coupled TIA circuit for my application. Application Specifications: Transimpedance gain: ~40kΩ Signal bandwidth: 4–6 MHz optical signal To prevent saturation due to…

  • RE: OPA892: Bias voltage dropping out

    Hi Oliver, We would love to hear your feedback for the Analog Circuit Design Studio Tools: on its usability, accuracy and any improvements you'd suggest. Please let us know your thoughts! Thanks Aditya Gosavi

  • RE: JFE2140: OPA892

    The forum seems picky on which type of files can be attached. I renamed my JFEx140.asy to JFEx140.asy.txt to allow attachment. I use the ASY file as the symbol and then the jfex140.lib as the model with the LTspice statement ".include jfex140.lib".…

  • OPA891: OPA891 and OPA892

    Part Number: OPA891 Other Parts Discussed in Thread: OPA892 , , OPA2892 Hello Experts, This board will be used for designing a probe for measuring switching currents of a high-speed SOC. The input voltage range is expected as 250uV to 7.5mV. OPA891 and…

  • OPA862: It is not a differential output.

    Part Number: OPA862 Other Parts Discussed in Thread: OPA892 Tool/software: The signal input to the OPA862 is generated by an oscillator. The circuit generated by the ICM7555 had differential outputs. On the other hand, the circuit generated by the SIT2001BC…

  • RE: OPA659: OPA659 spice model

    Hi Igancio, Is there a tutorial on how to import an op amp package (provided by TI) into TINA? IT has been very difficult to do that with opa892. I put in a ticket to get in touch with you about this, but never heard back. Thanks!

  • RE: OPA2210: OPA2210

    Sumeet, Assuming a bandpass filtering shown below, using OPA892 with its broadband noise below 1nV/rt-Hz would result is the input referred noise of around 152nVrms (1.52mV/10,000) and thus could be able to measure a piezo signal in hundreds of nV - see…
