ON Semiconductor LM393EDR2G - Dual Differential Comparator

The LM393EDR2G from ON Semiconductor is a dual differential comparator that is designed to provide a precise and cost-effective solution for applications requiring voltage level detection and signal conditioning. This integrated circuit (IC) is part of the LM393 series, and it is widely used in a variety of electronic systems due to its reliability, versatility, and low power consumption.

Key Features

• Low Power Design: The LM393EDR2G operates with a very low current drain, which is typically 0.8 mA, making it ideal for battery-powered devices.
• Wide Voltage Range: This comparator can operate from a single power supply over a wide range of voltages, from 2 V to 36 V, or from dual supplies of ±1 V to ±18 V.
• Dual Comparators: It contains two independent precision voltage comparators with an offset voltage specification as low as 2 mV max for two comparators, which is obtained by trimming at the wafer level.
• Output Compatibility: The open collector outputs can be connected to other open-collector outputs to achieve wired-AND relationships.
• Low Input Bias Current: Input bias current is typically 25 nA, which is ideal for high-impedance sensing applications.
• Fast Response Time: The response time specified is as fast as 1.3 µs for TTL level input step, making it suitable for high-speed applications.
