LM224ADR

Overview

The LM224ADR is a quad operational amplifier manufactured by Texas Instruments, housed in a 14-SOIC surface-mount package. It features a gain-bandwidth product of 1.2 MHz and a slew rate of 500 mV/us. The device operates on a single supply voltage ranging from 3 V to 32 V, or dual supplies from ±1.5 V to ±16 V. Key electrical specifications include an input offset voltage of 5 mV, input bias current of 150 nA, and a common-mode rejection ratio of 80 dB. Each channel provides an output current capability of 20 mA with a quiescent current of 1.4 mA per channel.

Feature Summary

• Integrates four independent high-gain operational amplifiers within a compact SOIC-14 package for space-constrained designs.
• Supports wide single-supply operation from 3 V to 32 V, enabling direct interfacing with standard logic levels.
• Delivers stable performance across the commercial temperature range of -25°C to +85°C.

Applications

• Transducer signal conditioning
• Active filtering circuits
• Voltage comparators

Procurement Notes

Verify the specific suffix 'R' indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected component matches the required temperature grade and pinout configuration for your PCB layout.

Selection Notes

Select this component for applications requiring multiple amplifiers in a small footprint without shutdown functionality. Compare input offset voltage and bias current requirements against other LM224 variants if higher precision is needed. Verify that the 20 mA output drive capability meets the load requirements of your specific circuit design.

Part Context

This part belongs to the LMx24 family of quad operational amplifiers produced by Texas Instruments. It shares architectural similarities with the LM124 and LM324 series but offers specific performance characteristics tailored for general-purpose analog signal processing tasks in industrial and consumer electronics.
