LM124DRG4

Overview

The LM124DRG4 is a quad general-purpose operational amplifier manufactured by Texas Instruments. It features four independent amplifiers within a single 14-pin SOIC package, designed for high gain applications. The device operates with a supply voltage range from 3 V to 32 V and supports dual supplies of ±1.5 V to ±16 V. Key electrical characteristics include a gain-bandwidth product of 1.2 MHz, a slew rate of 500 mV/µs, and an input bias current of 10 nA. It maintains functionality across an extended temperature range of -55°C to +125°C.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to ensure correct packaging configuration. Confirm RoHS compliance status directly with official datasheets as regulatory requirements may vary by production batch. Cross-reference the full part number with authorized distributor catalogs to validate availability and technical specifications before procurement.

Selection Notes

Select this component when multiple independent amplification channels are required in a space-constrained design. The wide supply voltage range accommodates various power architectures without level shifting. Ensure the thermal performance of the SOIC-14 package meets the application's dissipation requirements under maximum load conditions.

Part Context

This device belongs to the LM124 family of quad operational amplifiers produced by Texas Instruments. It serves as a robust solution for multi-channel analog processing needs. The DRG4 suffix indicates a specific tape-and-reel packaging variant optimized for automated surface-mount assembly processes.

Replacement Considerations

Official substitutes include LM124DR and LM124DRG4 variants from Texas Instruments. Verify pin compatibility and electrical parameter alignment before substitution.
