LM311P Generic 10pcs DIP‑8 Voltage Comparator IC – Precision Low‑Power

Description

Product Overview

The LM311P is a classic voltage comparator designed for reliable operation in demanding industrial environments. Packaged in a 10‑piece DIP‑8 tray, each unit measures 0.39 x 0.39 x 0.39 inches and weighs only 0.04 ounces, making it easy to integrate into dense PCB layouts. Manufactured by Generic, the LM311P offers high input impedance, fast response time, and low quiescent current, ensuring accurate voltage threshold detection while minimizing power consumption. Its open‑collector output stage provides flexibility for interfacing with a variety of load conditions, and the device operates over a wide supply voltage range, supporting both 5 V and 15 V systems. The comparator’s temperature range of –40 °C to 85 °C guarantees stable performance across typical industrial temperature variations. Detailed specifications, including input offset voltage, bias current, and propagation delay, are documented in the datasheet, allowing engineers to design precise control loops, level‑shifting circuits, and protective monitoring systems with confidence.

Usage

Designed for signal conditioning, the LM311P excels in applications such as sensor interface circuits, power‑management modules, and automation control panels. Its low‑power operation makes it suitable for battery‑powered devices, while the fast switching capability supports high‑frequency PWM generation and pulse‑width modulation schemes. Typical usage scenarios include temperature sensor threshold detection, over‑voltage and under‑voltage protection, and comparator‑based oscillators for timing functions. The DIP‑8 form factor simplifies prototyping and mass production, allowing designers to quickly populate boards using standard through‑hole assembly processes. The device’s robust electrical characteristics also make it a reliable choice for automotive diagnostics, industrial motor control, and renewable energy inverter monitoring, where precise voltage comparison is essential for safe and efficient operation.
