Overview
The LM124AQDRDL is a quad operational amplifier manufactured by Texas Instruments, designed for high-reliability applications. It features four independent amplifiers within a single package, offering a gain-bandwidth product of 1.2 MHz and a slew rate of 0.5 V/µs. The device operates with a supply voltage range from 3 V to 36 V and supports an output current of up to 20 mA per channel. It is housed in a 14-VSSOP package and rated for an extended operating temperature range of -55°C to 125°C.
Feature Summary
- Quad operational amplifier configuration for multi-channel signal processing
- Extended industrial and automotive temperature rating for harsh environments
- Single-supply or dual-supply operation capability
- Internal frequency compensation for stability
Applications
- Industrial process control systems requiring high reliability
- Automotive sensor signal conditioning circuits
- Battery-powered equipment due to low quiescent current
- Transducer amplification in aerospace applications
Procurement Notes
Verify the specific 'A' grade qualification and moisture sensitivity level (MSL) requirements against your assembly line standards. Confirm that the VSSOP-14 package dimensions match your PCB footprint exactly. Ensure the supplier provides traceability documentation suitable for automotive or aerospace quality standards if applicable.
Selection Notes
Select this component when high reliability and wide temperature tolerance are critical compared to commercial grade parts. Consider the LM124AQDRDL over standard LM124 variants if your design requires AEC-Q100 compliance or enhanced long-term stability. Evaluate the trade-off between the 1.2 MHz bandwidth and power consumption for your specific application needs.
Part Context
This part belongs to the LM124 family of quad operational amplifiers, which are industry-standard devices known for their versatility. The 'AQ' suffix typically denotes an automotive-grade or high-reliability variant with stricter manufacturing controls. It serves as a robust alternative to general-purpose op-amps in demanding electronic systems where failure is not an option.
Replacement Considerations
Official substitutes include other LM124 family members such as LM124QDR or LM124QDRQ1 if automotive qualification is required. Verify pin compatibility and electrical parameter overlaps before substitution. Consult Texas Instruments for qualified replacement lists to ensure performance equivalence.
