What are the key features of LM324ADRG4?
- Quadruple op-amp in a single package — four independent operational amplifiers sharing one device for space-efficient designs
- Improved offset voltage — enhanced input offset performance over standard LM324 for higher accuracy in precision signal conditioning
- Wide common-mode input voltage range — 65 dB min / 80 dB typical CMRR enables robust rejection of common-mode noise
- Low bias current — max 0.2 µA IIB reduces loading on high-impedance sources in sensor interface applications
- Internal frequency compensation — stable single-supply or split-supply operation without external compensation components
What is LM324ADRG4 used for?
The LM324ADRG4 is widely used in industrial sensor signal conditioning, active filter design, and instrumentation amplifier circuits where four op-amp channels are needed in a compact footprint. Its low bias current and improved offset make it ideal for precision analog front-ends in data acquisition systems, battery-powered portable equipment, and comparator applications. The device also suits audio preamplifiers, transducer amplifiers, and DC gain stages in automotive and consumer electronics.

Frequently Asked Questions
What are the key electrical specifications of the LM324ADRG4?
The LM324ADRG4 features a minimum common-mode rejection ratio of 65 dB (80 dB typical), a maximum input bias current of 0.2 µA (0.1 µA at 25°C), and a maximum input offset current of 0.075 µA. It uses a voltage-feedback architecture with internal frequency compensation for stable operation across supply configurations.
What are the typical applications for the LM324ADRG4?
The LM324ADRG4 is commonly used in active filters, sensor signal conditioning, instrumentation amplifiers, transducer amplifiers, DC summing amplifiers, and comparator circuits. Its quad op-amp configuration makes it ideal for multi-channel analog signal processing in industrial, automotive, and consumer electronic systems.
What package does the LM324ADRG4 come in and what does the 'G4' suffix mean?
The LM324ADRG4 is available in a Small Outline (SOIC) surface-mount package. The 'DR' suffix denotes the SOIC-14 package, while the 'G4' suffix indicates it meets Texas Instruments' green/RoHS-compliant packaging requirements, meaning it is lead-free and halogen-free.
Is the LM324ADRG4 compatible with single-supply operation?
Yes, the LM324ADRG4 is designed to operate from a single supply as well as split (dual) supplies. This flexibility makes it suitable for battery-powered and single-rail designs where a negative supply rail is not available, simplifying power supply design in portable and embedded applications.
What are common alternatives or replacements for the LM324ADRG4?
Compatible alternatives include the standard LM324DR, the LM2902 (lower voltage version), and higher-performance replacements such as the TLV2374 or OPA4374 from Texas Instruments for improved offset voltage and bandwidth. Always verify pin compatibility and supply voltage range when substituting parts.
