  • OPA2890: 1 to 4 fanout

    TI Thinks Resolved
    Part Number: OPA2890 Dear Sir/Madam, I am after some PCB routing advice on connecting one OPA2890 (gain of 2) to four OPA2890 (gain of 1). The delay between the OPA2890 is not important just signal quality. Regards Joe

  • OPA2890: Some further BP active filter testing the DABP topology

    Resolved
    Part Number: OPA2890 Before I leave this newer (to me) BP filter topology, I stepped through a more demanding design targeting total 6dB gain with 1MHz center and only 50kHz BW forcing a 4th order solution in Filterpro. It does not support this topology…

  • RE: LMH6643: Slew rate

    Resolved
    So you are doing a buffer? A 10MHz 2Vpp sinusoid requires a peak dV/dT of 62.8V/usec. If you can use a 5V part, use the OPA2837 - if you need a 10V total supply, use the OPA2890
