SG1731J/883B

The SG1731J/883B is designed as one kind of DC motor pulse width modulator device that provides a bi-directional pulse train output in response to the magnitude and polarity of an analog error signal input. And this device is useful as the control element in motor-driven servo systems for precision positioning and speed control.

Features of the SG1731J/883B are:(1)+/-3.5V to +/-15V control supply; (2)+/-2.5V to +/-22V driver supply; (3)Dual 100mA source/sink output drivers; (4)5 KHz to 350 KHz oscillator range; (5)High slew rate error amplifier; (6)Adjustable deadband operation; (7)Digital SHUTDOWN input.

The absolute maximum ratings of the SG1731J/883B can be summarized as:(1)Supply Voltage (±VS): ±18 V;(2)Analog Inputs: ±VS;(3)Digital Inputs (SHUTDOWN): -VS-0.3V to -VS+18V;(4)Output Driver Supply Voltage: ±25 V;(5)Source/Sink Output Current (continuous): 200 mA;(6)Source/Sink Output Current (peak, 500ns): 400 mA;(7)Output Driver Diode Current (continuous): 200 mA;(8)Output Driver Diode Current (peak, 500 ns): 400 mA;(9)Operating Junction Temperature: 150°C;(10)Storage Temperature Range: -65°C to 150°C;(11)Lead Temperature (Soldering, 10 Seconds): 300°C.
