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…
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.

Part Number: INA180 Other Parts Discussed in Thread: TIDA-00472 , , INA241A , INA241B , INA240 , INA181 , OPA374 Hello,
We designed a board to drive a BLDC motor with a 16.6V 15amps supply battery.
We would like to implement Cycle by cycle current…
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…
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…
The OPA145 also looks like a good choice, this file has not been recently updated so the OPA196 is not in yet, and the pricing is out of date.

to User473,
I searched all the op amp portfolio with the parametric search (precision, general purpose, and high-speed). There are 6 options with temperatures of 150C and above (see attached). The best match is the OPA211-HT (210C max). This is the…
