Hello Hironari,
The reason why devices such as the DRV421 are not paired with the PGA300 is that these are very different devices.
The DRV421 is a fluxgate current sensor and the PGA300 is a Signal Conditioner and Transmitter for Pressure Sensors.

Part Number: DRV421 Other Parts Discussed in Thread: DRV411 Tool/software: Hi everyone,
does anybody know in which case the optional schottky diodes are needed? And what is the purpose of this? If I use an external amplifier (supplied by +/-15V), then…
Hello Ajay,
Until you provide the details that Javier is asking for, we have no information to troubleshoot your circuit. I am going to change the status of this thread to waiting for customer as we cannot troubleshoot in the dark.
Please provide the…
Part Number: DRV421 Hello All
- We are working with DRV421. Looking to the user manual, ER asserts low when having a demagnetization cycle.
- We have performed some measurement monitoring OR and ER pin. In the below scope screenshot, in yellow is OR pin…
Part Number: DRV421 Hello technical team,
I want to implement a circuit based on DRV421 for closed loop application. I want to know the parameters of the coil integrated internally in the DRV421.
Part Number: DRV421 Other Parts Discussed in Thread: DRV411 , TIPD184 Hi Support team,
do you have a simulation model for DRV421? It would be great for LTspice. If not, could you tell me how I can simulation the output signal of Icomp1 and Icomp2? I tried…
Part Number: DRV421 Hello E2E Experts,
Good day.
We are in the late stage of the development of a Residual Current Monitoring device (IEC62752 compliant) using the DRV421 IC. Recently, we performed high-low temperature tests on the device and discovered…
Part Number: DRV421 Hello. DRV421 can be used aven in +/-15V applications (datasheet point 8.2.3).
However an external driver is nesessary because of the limits of the chip. What driver do you suggest? I suppose operational amplifier followed by npn+pnp…
Part Number: DRV421 Hello
I'm designing a current sensor using the DRV421that seems to work very well
My question is : if I have only to measure positive currents what is the best way to get a 0/5V signal (0V-->Imin=0Ampere 5-->Imax)?
Should…
