ON Semiconductor LM393SNG Dual Differential Comparator

The LM393SNG is a versatile dual differential comparator produced by ON Semiconductor, designed to provide a reliable solution for a wide range of applications that require voltage comparison. This integrated circuit is engineered to operate from a single power supply over a wide range of voltages, or from dual supplies for systems that require a more flexible power scheme.

Encased in a standard 8-pin DIP package, the LM393SNG is a convenient choice for space-conscious designs. Its design is optimized for low power consumption while still delivering high performance, making it an ideal choice for battery-operated devices.

Key Features:

• Low Input Bias Current: The device features a low input bias current, which is a significant advantage in precision applications, as it minimizes the effect on the input signal.
• Low Input Offset Voltage: The LM393SNG offers a low input offset voltage, which enhances the accuracy of the comparator by allowing it to detect smaller differences between the input voltages.
• Wide Supply Voltage Range: This comparator can be powered by a supply voltage ranging from 2V to 36V when using a single supply, or ±1V to ±18V when using a dual supply, providing flexibility in various application designs.
• Low Power Consumption: Designed with power efficiency in mind, it is suitable for battery-operated devices due to its low power draw.
• Open Collector Outputs: The open collector output configuration allows for wired-AND connections and the ability to connect to different voltage levels, provided that they are within the power supply range.
• Common Mode Input Voltage Range: The comparator includes a common mode input voltage range that includes ground, making it ideal for single-supply operations.
• Output Compatible with TTL, MOS, and CMOS: The output can directly interface with TTL, MOS, and CMOS without the need for pull-up resistors, simplifying the design and reducing component count.
