LM193DR

LM193DR Description

The LM193DR from Texas Instruments is a dual differential comparator designed for general-purpose applications, offering high precision and reliability in a compact 8-SOIC surface-mount package. This active, RoHS3-compliant device operates over a wide voltage range (2V–36V single supply, ±1V–18V dual supply), making it versatile for various circuit designs. With a low input offset voltage (max 5mV @ 30V) and minimal input bias current (0.1µA @ 5V), it ensures accurate signal comparison while maintaining low quiescent current (max 2.5mA) for power efficiency. Packaged in Tape & Reel (TR), it is ideal for automated assembly processes.

LM193DR Features

• Dual Comparator Design: Two independent comparators in a single package, reducing board space and cost.
• Wide Supply Range: Supports 2V–36V (single) or ±1V–18V (dual), accommodating diverse power requirements.
• Low Power Consumption: Quiescent current ≤2.5mA enhances energy efficiency.
• High Precision: 5mV max offset voltage and 0.1µA input bias current ensure reliable performance in sensitive circuits.
• Robust Packaging: MSL 1 (Unlimited) moisture sensitivity and surface-mount (SOIC-8) compatibility suit industrial environments.
• Output Current Capability: 20mA sink/source for driving LEDs, relays, or logic gates.

LM193DR Applications

The LM193DR excels in precision comparison tasks, including:

• Voltage Monitoring: Over/under-voltage detection in power supplies and battery management systems.
• Signal Conditioning: Window comparators for sensor interfaces (e.g., temperature, light).
• Industrial Control: Threshold detection in motor drives and automation systems.
• Consumer Electronics: Used in audio level indicators, PWM generation, and logic-level shifting.
• Automotive Systems: Reliable operation in harsh environments due to wide temperature tolerance.
