Product Overview & Engineering Notes
Product Description:
The LM324DR is a quad general-purpose operational amplifier manufactured by Texas Instruments. It integrates four internally compensated independent operational amplifiers into a single SOIC-14 package, offering low power consumption and stable performance for a wide range of analog signal conditioning applications. The LM324DR supports both single-supply and dual-supply operation, with input common-mode voltage extending to ground, making it an excellent choice for sensor interfaces, active filters, voltage followers, and embedded analog circuits. Its surface-mount package is well suited for modern automated PCB assembly and high-volume manufacturing.
Core Application Areas:
- Industrial Control: Signal conditioning, instrumentation, and process monitoring.
- Sensor Interfaces: Temperature, pressure, current, and voltage sensor amplification.
- Power Management: Battery monitoring, voltage regulation, and feedback control loops.
- Consumer Electronics: Audio preamplifiers, active filters, and analog processing circuits.
- Embedded Systems: ADC front-end circuits, comparator applications, and general analog signal amplification.
Engineering Selection Guide:
- Quad Op Amp Integration: Four independent amplifiers reduce PCB space and overall component count.
- Wide Operating Voltage: Supports 3V to 30V single supply or ±1.5V to ±15V dual supply, suitable for a broad range of applications.
- Surface Mount Design: The SOIC-14 package is optimized for automated SMT production and compact PCB layouts.
- Reliable General-Purpose Performance: The LM324DR is ideal for low-frequency analog applications where low power consumption and stable operation are required.
- Upgrade Path: For improved accuracy, lower offset voltage, and enhanced EMI performance, designers may consider LM324B or other newer TI operational amplifiers.
Supply Status:
The LM324DR remains an active product in Texas Instruments’ operational amplifier portfolio. Thanks to its mature design, competitive cost, and wide industry adoption, it continues to be one of the most commonly specified quad operational amplifiers for industrial, commercial, and embedded electronic designs.
