HI
We are building a stepper motor position accuracy tester can we use OPA548 to produce a linear driver for motor, so that we can drive both phases with a current source which will be programmed from the test application.
I need to produce the sine and cosine currents. So we are planning to use OPA548 with a shunt resistor for monitoring the current (which will act as the feedback for the amplifier).
Please confirm can I use this configuration.
Regards,
Anoop
