Overview
The LM124D is a quad operational amplifier manufactured by Texas Instruments, belonging to the LM124 series. It features four independent high-gain amplifiers with internal frequency compensation. The device 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 a maximum input offset voltage of 7 mV. It supports an operating temperature range from -55°C to +125°C and is available in a 14-SOIC package.
Feature Summary
- Four independent high-gain operational amplifiers with internal frequency compensation
- Wide single-supply voltage operation from 3 V to 30 V
- Input common mode voltage range includes ground
- Low input bias current of 20 nA typical
Applications
- Transducer amplifiers for sensor signal conditioning
- DC gain blocks requiring stable low-power performance
- All active filter designs utilizing general-purpose op-amps
- Voltage comparators in single-supply systems
Procurement Notes
Verify the specific suffix against official manufacturer documentation to confirm package type and temperature grade. Ensure the ordering part number matches the required industrial specifications. Cross-reference datasheet revisions for any changes in mechanical dimensions or electrical limits before finalizing procurement.
Selection Notes
Select this component when a quad amplifier configuration is required for cost-sensitive single-supply applications. It is suitable for designs needing moderate bandwidth and low quiescent current. Compare input offset voltage and bias current requirements against other series members if higher precision is necessary.
Part Context
The LM124D is part of the broader LM124 family, which includes variants like LM124J and LM124DR. These devices share the same core quadruple operational amplifier architecture but differ in packaging and thermal ratings. The D suffix typically denotes a surface-mount SOIC package, distinguishing it from through-hole or ceramic DIP options within the same functional family.
Replacement Considerations
Official substitutes include LM124DR and LM124DRG4 from Texas Instruments. Verify pinout compatibility and electrical parameter equivalence before substitution. Ensure the replacement part meets the same temperature and packaging requirements as the original design specification.
