LM224DRG4

Overview

The LM224DRG4 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 of 20 mA with a quiescent current of 1.4 mA per channel. The component functions within a temperature range of -25°C to +85°C.

Feature Summary

• Integrates four independent high-gain operational amplifiers into a single compact package for space-constrained designs.
• Supports operation from a single power supply or split dual supplies, offering flexibility in various circuit configurations.
• Features rail-to-rail input capability to maximize dynamic range at low supply voltages.

Applications

• Transducer amplification
• Active filtering
• Voltage comparators

Procurement Notes

Verify the specific suffix G4 indicates RoHS compliance and green material status when sourcing. Confirm the SOIC-14 package dimensions match your PCB footprint requirements. Ensure the operating temperature range of -25°C to +85°C aligns with your environmental conditions. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a quad amplifier configuration is required for general-purpose signal conditioning. Consider the 1.2 MHz bandwidth and 500 mV/us slew rate for moderate-speed applications. Evaluate the 5 mV input offset voltage against your precision requirements. Compare the 20 mA output drive capability with load demands before finalizing the design choice.

Part Context

This part belongs to the LMx24 family of quad operational amplifiers from Texas Instruments. It shares architectural similarities with the LM124 and LM324 series but offers specific commercial-grade temperature ratings. The DRG4 designation identifies the tape-and-reel packaging format suitable for automated surface-mount assembly processes.

FAQ

Does the LM224DRG4 support rail-to-rail output?

No, the datasheet specifies rail-to-rail input capability only; the output does not swing fully to the positive rail.

What is the maximum supply voltage for this device?

The maximum single supply voltage is 32 V, which corresponds to a maximum dual supply voltage of 16 V.
