LM324DR

LM324DR Description

The LM324DR from Texas Instruments is a quad general-purpose operational amplifier (op-amp) housed in a 14-SOIC surface-mount package. Designed for versatility, it operates over a wide supply voltage range of 3V to 30V, making it suitable for both single and dual-supply applications. With a gain bandwidth product of 1.2 MHz and a slew rate of 0.5V/µs, it delivers stable performance for low-frequency signal conditioning and amplification tasks. The device features low input bias current (20 nA) and moderate input offset voltage (3 mV), ensuring accuracy in precision circuits. Its ROHS3 compliance and REACH unaffected status make it environmentally friendly, while the MSL 1 (Unlimited) rating ensures reliability in storage and handling.

LM324DR Features

• Quad Op-Amp Configuration: Integrates four independent amplifiers in a single package, reducing board space and cost.
• Wide Supply Range (3V–30V): Supports diverse power configurations, including battery-operated systems.
• Low Power Consumption: Draws 1.4mA per channel, ideal for energy-sensitive designs.
• High Output Current (30 mA/channel): Capable of driving heavier loads compared to similar op-amps.
• Extended Temperature Range (0°C to 70°C): Reliable performance in industrial and consumer environments.
• Surface-Mount Design (SOIC-14): Facilitates compact PCB layouts and automated assembly.

LM324DR Applications

The LM324DR excels in analog signal processing, including:

• Sensor Signal Conditioning: Amplifying outputs from thermocouples, strain gauges, or photodiodes.
