Remark

LM311DR General Description

The LM311DR is a voltage comparator integrated circuit (IC) manufactured by Texas Instruments. It operates from a single power supply over a wide range of voltages, typically from 5V to 30V. The device is designed for use in applications requiring high-speed voltage comparisons, such as in oscillators, level detectors, and pulse-width modulators.With its open-collector output, the LM311DR can interface with a variety of logic circuits, allowing flexibility in system design. It offers fast response times, making it suitable for time-critical applications. The LM311DR features differential inputs and can operate over a wide temperature range, typically from -25°C to 85°C, making it suitable for various environmental conditions.The "DR" suffix indicates that the IC comes in a small outline package (SOIC) with dual-row pin configuration, facilitating easy integration onto printed circuit boards. Additionally, it offers improved specifications over its predecessor, ensuring reliable performance in demanding applications.

Features

LM311DR is a voltage comparator with an input common-mode voltage range from -0

5V to 36V, an output voltage swing that goes to VCC-1

5V, and a response time of 165 ns

It operates from a single 5V to 30V power supply or from dual supplies of ±2

5V to ±15V

Application

LM311DR, a voltage comparator, finds application in voltage monitoring, pulse-width modulation, and waveform shaping due to its high-speed operation and wide voltage range

Additionally, it's used in voltage level detection circuits, switching power supplies, and motor control systems for its precise performance and versatility
