In the circuit using A3977 to drive the stepper motor, there are some parts of the circuit analysis that I don't understand. I hope you can give me some advice. [img]data:image/png;base64,iVBORw0KGgoA
[size=14px]As the title says, I have finished drawing the circuit, and my boss asked me to output the circuit ICT and FCT specifications. How can I do this? I looked it up on Baidu, and I found that I
1. AD8138 can be used to achieve
The single-ended to differential conversion circuit uses AD8138 from AD. This amplifier has a wide analog bandwidth (320MHz, -3dB, gain 1) and can realize the function
