Linear Comparators

LM293MDREP Description

The LM293MDREP from Texas Instruments is a dual general-purpose differential comparator designed for precision voltage comparison in a wide range of applications. Packaged in an 8-SOIC surface-mount format and supplied in Tape & Reel (TR), it is optimized for automated assembly. This ROHS3 Compliant and REACH Unaffected device operates over a 2V to 36V single-supply or ±1V to ±18V dual-supply range, making it versatile for industrial, automotive, and consumer electronics. With a low quiescent current (max 2.5mA) and high output current capability (20mA typ), it balances power efficiency with robust drive performance.

LM293MDREP Features

• Low Input Offset Voltage: Max 5mV at 30V, ensuring high accuracy in signal comparison.
• Wide Supply Range: Supports 2V–36V (single) or ±1V–±18V (dual), ideal for battery-powered and industrial systems.
• Low Bias Current: 0.25µA max at 5V, minimizing load on signal sources.
• High Output Drive: 20mA sink/source current, capable of driving relays, LEDs, or small loads directly.
• Robust Packaging: MSL 1 (Unlimited) moisture sensitivity, suitable for extended storage and harsh environments.
• Dual Comparator Design: Two independent comparators in a compact 8-SOIC, saving board space.

LM293MDREP Applications

• Battery Management Systems: Voltage monitoring and protection due to wide supply range and low power consumption.
• Industrial Control: Threshold detection in PLCs, motor control, and sensor interfaces.
• Automotive Electronics: Window comparators for overvoltage/undervoltage detection in ECUs.
• Consumer Electronics: Signal conditioning in audio equipment, power supplies, and level shifting.
• Embedded Systems: GPIO expansion or logic-level translation in microcontrollers.

Conclusion of LM293MDREP

The LM293MDREP excels in precision, versatility, and reliability, offering a low-power, high-performance solution for voltage comparison tasks.
