Question

2. We are using the Toshiba ULN2003APG Darlington Array and full-step drive.

a.

b.

What is the maximum speed of the output shaft (after the gearbox) with a supply voltage of +5 Volt?

Suggest a method for maximizing the speed. You can increase the supply voltage up to the safety

limits of the driver.

Hint: An alternate Darlington array may be used to improve your performance:
