ADMC201AP

Product Summary

The ADMC201AP is a motion coprocessor that can be used with either microcontrollers or digital signal processors (DSP). The ADMC201AP provides the functionality that is required to implement a digital control system. In a typical application, the DSP or microcontroller performs the control algorithms (position, speed, torque and flux loops) and the ADMC201AP provides the necessary motor control functions: analog current data acquisition, vector transformation, digital inputs/outputs, and PWM drive signals.
