The LM193D is a versatile and robust device from Texas Instruments (TI), designed to cater to a broad array of applications requiring voltage comparison. This integrated circuit is part of the LMx93 series, which are low-power, dual-voltage comparators. The LM193D version specifically comes in a SOIC package, which is suitable for surface-mounted technology (SMT) applications.

Key Features

• Dual Comparators: The LM193D contains two independent voltage comparators that allow for simultaneous comparison of two separate input voltages against a reference voltage.
• Wide Supply Voltage Range: It operates from a single power supply over a wide range of voltages, from 2V to 36V, or a dual supply of ±1V to ±18V, making it highly adaptable to various circuit designs.
• Low Supply Current: The device is designed for low-power operation, which is crucial for battery-powered and energy-efficient applications.
• Offset Voltage: The LM193D offers a typical input offset voltage of 2mV, which ensures precise voltage comparison and stable operation.
• Input and Output Characteristics: It features a differential input voltage range equal to the supply voltage and an output voltage compatible with TTL, MOS, and CMOS logic systems.
