  • LMP8481-Q1: lmp8481

    TI Thinks Resolved
    Part Number: LMP8481-Q1 Other Parts Discussed in Thread: LMP8481 Tool/software: I am using S version of the part. According to my circuit design at zero current, offset value is suppose to be 660mV(+- 5mV). I am achieving this in 999 out of 1000. But few…

  • LMP8481: Computing Current Sense Amplifier Error

    TI Thinks Resolved
    Part Number: LMP8481 Tool/software: Hello- I am using the -S and -T versions of the LMP8481 current sense amplifier. I am using TI's "Current Sense Amplifier Comparison and Error Calculator" https://www.ti.com/tool/CS-AMPLIFIER-ERROR-T…

  • RE: LMP8481: How to measure high current with LMP8481 on high side?

    Hi Jaiver, Thanks for guiding. Cx responded: Javier Contreras4 said: Have they tried multiple parts? Do they all behave the same? Yes, I tested the 3 lmp8481 alternately and the result is the same. I checked that the input voltages are correct. We are currently…

  • LMP8481: Unable to find current value

    TI Thinks Resolved
    Part Number: LMP8481 In my board the LMP8481 is not giving the proper output. From the data sheet the sense voltage can be found from vout voltage by the equation ( vsense = vout / gain). And I am using the LMP8481 H variant of the IC. So for a 2A current…

  • LMP8481-Q1: Datasheet Typo

    Resolved
    Part Number: LMP8481-Q1 Hi Team, While reviewing the LMP8481-Q1 datasheet, I noticed what appears to be a typo on page 11: I believe that value should be 0.1 µF as listed in other diagrams within this datasheet. I’m not sure if this error is in…

  • RE: INA240: Bidirectional Current sense -26V to +26V

    What power supplies do you have available? The LMP8481 would require ±30 V (because of its minimum 4 V input voltage).

  • LMP8481: Please explain LMP8481's Theory of Operation

    Resolved
    Part Number: LMP8481 The following is not understandable in LMP8481 DATASHEET 8.1.1 Theory of Operation. Can you explain it? Thank you! "Internally, the voltage on each input pin is converted to a current by the internal precision thin-film input res…

  • LMP8481: LMP8481 temperature drift on 1 in a 100

    TI Thinks Resolved
    Part Number: LMP8481 I have a design where i use the LMP8481 to sense a DC current. I made a 1000 boards and 10 of them have an issue where the output voltage at no current drifts as I increase the temperature with a heat gun. I have check if it was the…

  • LMP8481: LMP8481-H at voltages less than 10V and low Rload values

    Resolved
    Part Number: LMP8481 At 5V and low Rload, gain is low. Vcc is connected to Rsense as in your typical application schematic, page 1 of datasheet. My schematic Rsense= 0.1 ohm, RefA and RefB are grounded, unidirectional current flow Typical Iload= 1A, Rload…
