Analog Input Stepper Driver : 

JT322AN is analog input stepper motor driver, which can be driven by an external potentiometer or driver. Using the latest 32 DSP technology, providing precision 0.05A current setting unit , and taking advanced digital filtering techniques, anti-resonance technology and precision current control technology to make it implement precise smooth operation, extra low noise . It’s widely used in semiconductor, electronic processing equipment, medical and precision equipment.
Capable of driving Nema11, Nema14, Nema17 and Nema23 series of two-phase hybrid stepper motors.
