1. An integrated circuit for controlling at least one motor, comprising:

  • at least one digital position and speed circuit (DPS) for providing measurements of speed, position, and direction of the at least one motor, the at least one DPS being in signal communication with the at least one motor for receiving a pair of signals having a quadrature relationship; and

    at least one programmable gain amplifier (PGA) electrically coupled to the at least one motor, the PGA being configured to receive a feedback signal indicative of current flowing through the at least one motor and to apply a second signal to the at least one motor for adjusting the speed of the at least one motor.
