LM339DR SMD IC SOP14 TEXAS INSTRUMENTS LM339DR

Product Overview:

A quad differential comparator integrated circuit designed for industrial and general-purpose applications. The LM339 is a versatile device that features four independent comparators in a single package, capable of operating from a single power supply or split power supplies over a wide range of voltages.

Core Specifications:

• Manufacturer: Texas Instruments

• Package Type: TSSOP, SOIC, or PDIP (depending on version)

• Function: Quad Differential Comparator

• Input Channels: 4 Independent Comparators

• Operating Voltage Range: 2.0 to 36 Volts (or ±1V to ±18V)

Features:

• Low Supply Current: Each comparator consumes very little power, making it efficient for battery-powered devices.

• Wide Input Range: The common-mode input voltage range includes ground, allowing it to sense signals referenced to the negative supply rail.

• Flexible Output: The open-collector output can be easily interfaced with various logic families, including TTL, MOS, and CMOS.

• High Reliability: The improved "B" versions offer better electrical specifications, including lower input offset voltage, lower bias current, and faster response times.

Applications:

• Industrial Monitoring: Used in sensors and control circuits for robotic systems and power supplies.

• Consumer Electronics: Commonly found in household appliances and cordless power tools for voltage monitoring and signal processing.

• Digital Logic Systems: Useful for converting analog signals into digital-compatible signals for microcontrollers and processors.
