  • RE: OPA2376: Is this the best replacement for LMV821

    Resolved
    Thank you for taking the time to explain why the LMV821 is noisy. I will look more into the OPA397.

  • RE: TPS7B7702-Q1: Co-work with MCU ADC

    Hi Albert, Ah yes of course- the OPA397 is not yet auto-qualed., but the higher-performance version will be next year called OPA392. The best device at the moment then is probably OPA376-Q1, or OPA388-Q1 for ultra-low offset chopper amp. Regards, Mike …

  • RE: OPA2145: amplifier and other component selection

    Resolved
    Hi Marek Lis, Thanks for the info and recommendation on opamp. Now we have better understanding with parameter selection of opamp. Apart from "Input bias" and "Offset Voltage", do we need to consider anything else? Unfortunately OPA392 and OPA397 are…
