LM224DRG3

Overview

The LM224DRG3 is a quad operational amplifier from the LMx24 series manufactured by Texas Instruments. It features four independent high-gain amplifiers within a single package, designed for versatile analog signal processing applications. The device operates with a wide single-supply voltage range of 3 V to 32 V or dual supplies of ±1.5 V to ±16 V. Key electrical specifications include a gain-bandwidth product of 1.2 MHz and a slew rate of 500 mV/µs. Input characteristics specify an input offset voltage of 5 mV and input bias current of 150 nA. The output stage provides a short-circuit protected drive capability of 20 mA per channel. Common-mode rejection ratio is rated at 80 dB, with an input voltage noise density of 35 nV/√Hz. The component is housed in a 14-SOIC surface-mount package and supports an operating temperature range from -25°C to +85°C.

Feature Summary

• Integrates four independent high-gain operational amplifiers into a single compact package for efficient space utilization.
• Supports operation from a single power supply ranging from 3 V to 32 V or split dual supplies.
• Features internal frequency compensation to ensure stability without requiring external components.
• Includes short-circuit protection on output stages to safeguard against load faults.

Applications

• Transducer amplification for sensor signal conditioning
• DC gain blocks in measurement circuits
• Built-in test equipment signal processing

Procurement Notes

Verify the specific suffix 'G3' against official Texas Instruments documentation to confirm it denotes a valid manufacturing revision or tape-and-reel specification distinct from standard variants. Ensure the ordering part number matches the exact datasheet revision required for your design. Confirm RoHS compliance status directly through manufacturer channels as packaging details may vary by production batch.

Selection Notes

Select this component when a quad amplifier configuration is required for cost-sensitive designs. It serves as a direct pin-compatible alternative to the LM324 family but offers improved performance metrics such as lower input offset voltage and higher bandwidth. Consider the 14-SOIC package constraints for PCB layout and verify that the 20 mA output current meets the load requirements of the application circuit.

Part Context

The LM224DRG3 belongs to the LMx24 family of quad operational amplifiers produced by Texas Instruments. This series is widely recognized for its reliability and low power consumption in general-purpose analog applications. The 'LM224' designation indicates military-grade temperature range specifications compared to commercial variants, while the 'DR' suffix specifies the 14-lead SOIC surface-mount package type used for automated assembly.

Replacement Considerations

The LM224DR is a compatible standard variant within the same package and functional family. The LM324 series offers similar functionality but with different electrical characteristics suitable for commercial temperature ranges. Verify pinout compatibility and thermal performance before substituting with other quad op-amp models.
