TILM324DR

Overview

The LM324DR is a versatile quad-channel operational amplifier designed for cost-effective, general-purpose applications. It operates from a single power supply across a wide voltage range of 3V to 30V, eliminating the need for dual supplies in many designs. Its low supply current of 1.4mA for all four channels makes it suitable for battery-powered and portable electronics.

Why Choose This Part

The primary advantage is the ability to operate with a common-mode input voltage range that includes ground, allowing direct sensing of ground-referenced signals. It offers a balance of 1.2 MHz gain bandwidth and a low input bias current of 20nA in a compact 14-SOIC surface-mount package. The quad-channel configuration provides high functional density while maintaining a low typical quiescent current of 750uA per channel.

Applications

Getting Started

For rapid prototyping, the SOIC-14 package can be used with a standard SOIC-to-DIP adapter on a breadboard. Ensure the input signal stays within the specified range of -0.3V to 32V to prevent damage. Standard SPICE models are widely available for simulating gain and frequency response before PCB layout.
