  • RE: LMP2012: Thermocouple amplifier produces DC offset with 100kHz interference

    Hi Marcus, Marcus Hughan said: why do we see a DC offset on the output of the amplifier when there is ripple on the input? I do not know what your TC accuracy specification is. The ripple noises at the input is likely from the following components. …

  • LMP2012QML-SP: LMP2012 supply max rating failure mode.

    TI Thinks Resolved
    Part Number: LMP2012QML-SP Other Parts Discussed in Thread: LMP2012 Tool/software: Hello, I use an LMP2012, do we know what is the failure mode at output level when the supply reach or go higher than the max rating 5,8Vting ? Thx

  • LMP2012: Offset Voltage change over the full temperature range.

    Resolved
    Part Number: LMP2012 Other Parts Discussed in Thread: LMP2021 The LMP2012 shows a TCVIO of 0.015 μV/°C. However, figures 2 through 4 seem to conflict. If I use a vertical line for the supply or common mode, it looks like the offset voltage can…

  • LMP2012: Output saturation of one amplifier affects the output of the other amplifier output

    Resolved
    Part Number: LMP2012 We use one amplifier in the LMP2012 for signal conditioning and the other is used to drive an ADC. If the amplifier driving the signal conditioning drives a heavy current load, there is a corresponding small offset on the other amplifier…

  • 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…

  • LMP2012: Open loop gain curves

    TI Thinks Resolved
    Part Number: LMP2012 Hello, In the LMP2012 datasheet ( SNOSA71L –OCTOBER 2004–REVISED SEPTEMBER 2015 ), there are several open loop gain curves. Each curve presents the OLG as a function of a special parameter (RL, CL, Vs). All the curves look…

  • LMP2012QML-SP: Will device damage occur if voltage is applied to +input prior to supply voltage being applied?

    Part Number: LMP2012QML-SP Other Parts Discussed in Thread: LMP2012 Tool/software: Hello, I am using several LMP2012QML-SP's in a space application design. For one application in particular, we are using this device to measure board input supply…
