LM224D

Overview

The LM224D is a quad operational amplifier manufactured by Texas Instruments, housed in a 14-pin SOIC package. It features four independent high-gain amplifiers designed for single or dual power supply operation. The device supports a wide voltage range from 3V to 30V single supply or ±1.5V to ±15V dual supply. Key electrical characteristics include a gain-bandwidth product of 1.2 MHz and a typical slew rate of 0.5 V/µs. Input bias current is typically 20 nA with an input offset voltage of 2 mV. Operating temperature ranges from -40°C to 105°C.

Feature Summary

• Integrates four independent high-gain operational amplifiers within a single compact package
• Supports flexible power configurations using either single or dual voltage supplies
• Provides stable performance across extended industrial temperature environments

Applications

• General-purpose analog signal conditioning circuits
• Sensor interface and buffering applications
• Active filter designs requiring multiple stages

Procurement Notes

Verify the specific manufacturer designation as STMicroelectronics also produces an LM224D variant with slightly different specifications. Confirm the exact datasheet aligns with Texas Instruments documentation to ensure compatibility with intended circuit parameters. Check for RoHS compliance status and packaging type variations such as tube versus reel options before finalizing procurement orders.

Selection Notes

Select this component when a cost-effective quad amplifier solution is required for general-purpose applications. Consider the 1.2 MHz bandwidth and 0.5 V/µs slew rate for moderate-speed signal processing tasks. Ensure the chosen package variant matches the PCB layout requirements and that the operating temperature range meets the environmental constraints of the target application.

Part Context

This part belongs to the LM224 family of quad operational amplifiers, which are widely used in industrial and consumer electronics. The LM224 series offers a balance of performance and low power consumption. Variants like the LM224A provide tighter tolerance specifications, while the standard LM224 serves as a versatile baseline for general analog design needs.
