Part Number: DRV425 Hello,
I am currently working on a bus bar application of the DRV425 with the differential gradient field measurement circuit shown on page 27 of the datasheet.
My application has for example compensation currents of I1 = 5,734 mA…
Hello Rene,
That will work but there a concern.
The noise you will get peak to peak at 10kHz if you filter is about 1µT from each one of the DRV425. If you use the full bandwidth you will see more like 1.4µT per DRV425. See this post . Also…
Part Number: OPA2990 I am curious about ESD. Are the CMOS op amps more susceptible than the older Bipolar op amps? For example the OP275G (actually that one has a JFET front end).
Part Number: DRV425 If I place 3 of these orthogonal to each other and very close (package/PCB spacing), will they interfere with each other ? Will I be able to determine magnetic flux in 3D ?
Part Number: DRV425 Hi. We've placed these items in a temperature- and magnetic-controlled chamber for 2 weeks, cycling 5C to 38C:
1) 2 each EVM modules from TI
2) Custom boards with DRV425's (not Q1) using non-magnetic materials and conforming to…
Part Number: DRV425-BUSBAR-EVM Other Parts Discussed in Thread: DRV425 Hello
I am trying to measure the rms noise level of DRV425 using its evaluation kit. I am using 24 bits ADC and ADC's measured rms noise level is under 10uv, but when I am connecting…
Part Number: DRV425 Hello, I found the following article from 2018 (in attachment) regarding the behavior of DRV425 chips. I am interested in the problem illustrated in Figure 1. We have a fairly large number of such chips and after examining some of…
