ONLM324DR2G
Overview
The LM324DR2G is a quad-channel, general-purpose operational amplifier designed to operate from a single power supply over a wide voltage range of 3V to 32V. It features four independent, internally frequency-compensated amplifiers in a compact 14-SOIC package, making it a staple for cost-sensitive analog signal processing. The design includes a true differential input stage and a common-mode input range that extends to the negative rail, simplifying its use in single-supply systems.
Why Choose This Part
The LM324DR2G offers high density with four amplifiers per package while maintaining a low quiescent current of 1.2mA at 5V. It eliminates the need for external compensation and provides short-circuit protected outputs, enhancing circuit reliability. Its ability to operate down to a 3V supply allows for direct compatibility with common digital logic levels.
Applications
Key Specifications
Getting Started
To evaluate the LM324DR2G, place the 14-SOIC component on a standard SOIC-to-DIP adapter for breadboard prototyping. Ensure that decoupling capacitors are placed close to the Vcc pin, and note that while the inputs can go to ground in single-supply mode, the output swing is limited by the load current and supply rails. SPICE models are widely available for simulating gain and phase margins before PCB fabrication.
