  • 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: Thermocouple amplifier produces DC offset with 100kHz interference

    TI Thinks Resolved
    Part Number: LMP2012 Tool/software: Shown below is a thermocouple amplifier circuit implemented using the LMP2012. Using K type thermocouple, the circuit produces the expected response of ~ 2.77mV/°C. (gain of 67.67) In the same system there are…

  • 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 vary 10uV…

  • 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…

  • 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 very…

  • LMP2012: LMP2012 Bi-Polar or CMOS?

    TI Thinks Resolved
    Part Number: LMP2012 Other Parts Discussed in Thread: LMC6081 Quick questions: is LMP2012 is fully Bi-polar technology or if it is part CMOS technology. Let me know, thanks!

  • LMP2012: Offset calibration time

    Resolved
    Part Number: LMP2012 For an application requiring a very low offset opamp we are considering the LMP2012QML. One of the opamp’s electrical characteristics specified in the datasheet is the “offset calibration time”. It is however not very clear to me…

  • RE: Lmp2012: LMP2012 common-mode input voltage

    Resolved
    Hi Eren, There is no issue applying a negative voltage to the V- of the LMP2012. Your lower common-mode bound will shift with the supply accordingly (V-) -0.3V. In general, any op-amp can be operated in dual supply. It was likely specified as single…
