  • RE: OPA4387: OPA4387 Linearity

    Resolved
    Jonathan, Chopper amplifiers are an excellent choice for low offset, and low offset drift. However, the chopping calibration process generates current transients on the inputs of the amplifier that translate into input offset when large feedback and input…

  • RE: LMP2012: Current Sense Circuit fails in low temperature

    Resolved
    Hi Tim, As you correctly diagnosed, the LMP2012 is not rail-to-rail input. This can be seen in the spec. below: This spec. shows that the input common mode voltage must sit 1.8 V lower than the supply voltage. For 3.3 V supply then the input common mode…

  • RE: OPA376: OPA376 issue in high temperature

    Resolved
    HI Nathan, We discussed the issue on the OPA376. The datasheet shows the CMRR changes from 90dB @25C to 60dB @150C, at hot temperature, where CMRR is specified above V(-) supply. The datasheet offers no assurances for CMRR for voltage more negative than…

  • LMP2012: Settling time

    TI Thinks Resolved
    Part Number: LMP2012 Other Parts Discussed in Thread: OPA387 , OPA388 Hello, I have witnessed that the LMP2012 takes a long time to settle after the input signal switches from one value to another. This settling time and error depend on the amplitude of…
