  • DRV425: DRV425 : How to enhance the measurement result ?

    Resolved
    Part Number: DRV425 Other Parts Discussed in Thread: ADS1271 , OPA1632 Is it possible to use directly the shunt measurement (RSHUNT) to get a better overall measurement (less noise) using a different output amplifier than the one included in the chip…

  • DRV425: Follow up on DRV425: Recovery after large magnetic field.

    Resolved
    Part Number: DRV425 Dear Javier, I was still wondering about the problem of the sensor not recovering after a large field pulse when Rshunt would be smaller than some 35 Ohms. Today I noticed that on the PCB where the sensor was mounted on I used…

  • DRV425: DRV425 Differential mode

    TI Thinks Resolved
    Part Number: DRV425 Tool/software: I want to connect multiple DRV425 like described in the busbar application note but more than just one pair. Is there a way to do this? For example 4 DRV425 where 2 build one pair in differential mode and the second…

  • DRV425: DRV425 High Temperature/ Signal Quality Issue

    Part Number: DRV425 Tool/software: Hi, I am testing out the DRV425 (DRV425QWRTJRQ1) sensor for a magnetic field sensing application at high temperature and am having an issue where the sensor will operate to a temperature of 125-150C however randomly…

  • DRV425: R5 compensation resistor and RSHUNT design ?

    Resolved
    Part Number: DRV425 Hello, In the RSHUNT design stated in the DRV425 datasheet (chapter 6.3.2, page 23), with DRV1 connected to AINP, the resistor R5 (dummy shunt) resistor can compensate for the RSHUNT value to make the output amplifier diff gain very…

  • DRV425: How the internal REFERENCE variations impact the DIFFERNTIAL shunt measurement ?

    Resolved
    Part Number: DRV425 Hello, I found in the DRV425 datasheet (table page 5) that the common mode output voltage at DRV1 and DRV2 pins is typically the REFOUT Voltage. Can we deduce that a perfect RSHUNT differential measurement does not exhibit any…
