  • RE: DRV425: Constant VOUT

    Resolved
    Greg, Glad to hear it is working out. FYI, the 40-60nT is in the expected noise of the DRV425 at that frequency. See this post if interested. Let us know if you need anything else.

  • DRV425: Compensation coil driver

    Resolved
    Part Number: DRV425 I notice that the position of Rshunt differs in the DRV425 and DRV425EM datasheets (between DRV1 and COMP1 or DRV2 and COMP2, respectively). Based on the block schematic (Section 7.2 of the datasheet) it shouldn't make a difference,…

  • DRV425: PCB layout footprint

    Resolved
    Part Number: DRV425 I would like a get a footprint for the recommended PCB layout for the DRV425. I have an older version of Alium PCB ( Ver 6.9) layout software. This version will not work with the script files exported by the TI Ultralibrarian.

  • DRV425: Nulling Earth's Magnetic Field

    TI Thinks Resolved
    Part Number: DRV425 Hi......is there any way to remove or filter the DRV425's response to the earth's mag field? I'm attempting to detect low level AC-generated magnetic fields by increasing the value of R1 on the evaluation board, however, that…

  • DRV425: Oscillation Frequency ???

    Part Number: DRV425 As far as I know, fluxgates are always driven into saturation by means of a periodic signal. This requires an excitation coil and an oscillator. However, I cannot find these components in the principle sketch for the DRV425. Can someone…
