  • OPA2891: Propagation delay

    Part Number: OPA2891 Here the propagation delay is not mentioned. Can I estimate the delay? I want to know the delay theoretically.

  • OPA2891: OPA2891's -VCC pin shorts to GND when connected to a -15V supply and current draw verification

    Part Number: OPA2891 Other Parts Discussed in Thread: THS4032 Hi, I have a current amplifier circuit designed using THS4032. We later replaced it with OPA2891 (purely related to availability issues, not related to performance). We have observed the…

  • OPA2891: difference in temperature rise

    Resolved
    Part Number: OPA2891 Other Parts Discussed in Thread: OPA2156 , Hi, Why does the IC temperature rise more easily with OPA2891 than with OPA2156 (both SOIC packages)? Using the same circuit, I input a 25kHz square wave at ±5V. (The power supply is…

  • OPA2891: Low cost low noise input amplifier suggestion

    Answer Suggested
    Part Number: OPA2891 Other Parts Discussed in Thread: OPA891 Tool/software: Dears, Customer want to find low noise input amplifier (<1nV/hz) ,I find OPA2891/2892 can meet this request. But customer said that the price of OPA2891/2892 is too high, he…

  • THS4062: THS4062 Recommended Replace has Low Slew Rate

    Part Number: THS4062 Other Parts Discussed in Thread: OPA2891 I need to replace the THS4062ID due to obsolence. The TI webtool recommends the OPA291DR but this part has only 1/4 of the slew rate. It the THS4062CDR a good alternative? It seems to have…

  • OPA892: What is unity gain stable OPamp?

    Part Number: OPA892 Other Parts Discussed in Thread: OPA2892 , OPA891 , OPA2891 I am planning to use OPA2892 as a buffer and an integrator. When I simulated this, I found that the circuit is not working. Again the circuit is working with OPA891. I found…
