  • RE: LMH6643: Alternative device of LMH6643

    Thanks Michael, Seems like I had set the lower temp range too low at -55 for the parametric search. I agree the OPA2810 seems like the best alternative in this case, some other dual channel alternatives are the LMH6612 & LMH6619 ( although slew rate for…

  • OPA2365-Q1: Reliability with Vs=5.5V

    Resolved
    Part Number: OPA2365-Q1 Other Parts Discussed in Thread: LMH6619-Q1 , OPA2365 Hi Team, The OPA2365-Q1 datasheet lists Vs=5.5V as the test condition for some of the electrical specs. However, 5.5V is both the max recommended voltage and abs max of the device…

  • RE: Could you recommend some op-amps suitable for DCR sensing application?

    Hi Lucy, 1. If the THS4222 chip operates at a high temperature of 60 degrees, then it could be that the part is oscillating. Have you looked at the THS4222 output to see if there is an oscillating sine wave? 2. It is possible that the large pick at…

  • RE: How to find source and range of gain independent output voltage offset in 2-Amp instrumentation amplifier using LMH6643, OPA2830, OPA2301

    Hello Douglas, I think what your experiment / data shows is that the op amp input offset voltage can have either polarity (pos or neg). When you apply the negative supply to the VEE pin, you see that some devices outputs swing below ground, whilst single…
