DESCRIPTION
The SG1731 is a pulse width modulator circuit designed specifically for DC motor control. It provides a bi-directional pulse train output in response to the magnitudeand polarity of an analog error signal input. The device is useful as the control element in motor-driven servo systems for precision positioning and speed control, as well as in audio modulators and amplifiers using carrier frequencies to 350 KHz.

FEATURES
• ±3.5V to ±15V control supply
• ±2.5V to ±22V driver supply
• Dual 100mA source/sink output drivers
• 5KHz to 350KHz oscillator range
• High slew rate error amplifier
• Adjustable deadband operation
• Digital SHUTDOWN input
