LM124DG4

Overview

The LM124DG4 is a quad operational amplifier manufactured by Texas Instruments, featuring four independent high-gain amplifiers with internal frequency compensation. It operates from a single power supply ranging from 3 V to 30 V or split supplies of ±1.5 V to ±15 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. The device is housed in a 14-SOIC surface-mount package and supports an operating temperature range from -55°C to +125°C.

Feature Summary

• Four independent high-gain operational amplifiers with internal frequency compensation
• Wide single-supply voltage operation from 3 V to 30 V
• Low input bias current for reduced loading effects
• Input common-mode voltage range includes ground potential

Applications

• Transducer amplifiers for sensor signal conditioning
• DC gain blocks requiring stable low-frequency performance
• Integrators for analog computation circuits
• Standard operational amplifier configurations in industrial control systems

Procurement Notes

Verify the specific ordering suffix DG4 against the manufacturer's latest documentation to ensure compliance with current RoHS standards and material composition requirements. Confirm that the SOIC-14 package dimensions match the target PCB footprint design constraints before finalizing procurement orders.

Selection Notes

Select this component when a quad amplifier configuration is required within a compact surface-mount form factor. It is suitable for applications demanding wide single-supply voltage ranges and low quiescent current consumption. Ensure the design accommodates the specified input offset voltage and bias current parameters for optimal circuit accuracy.

Part Context

This part belongs to the LMx24 family of low-power quad operational amplifiers produced by Texas Instruments. The series is widely utilized in general-purpose analog signal processing tasks. The LM124 variant specifically denotes the military-grade temperature range extension compared to commercial counterparts, offering reliability across harsh environmental conditions.

Replacement Considerations

Direct pin-compatible replacements within the same family include the LM224DG4 and LM324DG4, provided their specific electrical parameter tolerances align with the original design requirements. Verify thermal performance and supply voltage limits when substituting between different grade variants.
