MOTOR SPEED CONTROL WITH MAX4295 CIRCUIT SCHEMATIC DIAGRAM

Resistor R1 biases the potentiometer to match the input range of U1. Full counter-clockwise rotation of the pot corresponds to maximum-speed reverse rotation of the motor. Mid-scale on the pot corresponds to motor off, and full clockwise rotation of the pot produces maximum-speed forward rotation in the motor.
