Hi Gagandip Singh Dadhwal,
I believe the best course of action would be to find out the gain of the amplifier used in the EVM for DRV8350.

Other Parts Discussed in Thread: OPA374 hi!
I am using OPA374 in differential configuration to sense motor current.
I have done DC simulation with same components i used in my circuit:
i added -9mv voltage source because the sense resistor is tied to…
Hey Tomer,
Javier is out of the office, but I will address your questions.
The INA180A1 (gain of 20 V/V) could replace the OPA374 (and surrounding feedback differential resistor network) because this is a DC return current configuration. The INA180A1…
Other Parts Discussed in Thread: BOOSTXL-DRV8301 , DRV8301-69M-KIT , OPA374 Hello, I have a question about the BOOSTXL-DRV8301 as reference to build my own hardware. What is the best position for the 1000pF capacitor over the differential measurement signal…
Hello Fabrice,
The LMV358 is NOT a rail-to-rail input device. It's input voltage range is limited to about 800mV below V+, or 2.5V. 2.7V is about where I would expect it to clamp. The LMV358 is working as expected!
Look at the "Input Common Mode Voltage…
