LM324 Quad Operational-Amplifier IC (DIP)

Overview: LM324 Quad Operational Amplifier IC (DIP)

The LM324 Quad Operational Amplifier IC integrates four independent, high-gain, frequency-compensated operational amplifiers in a single DIP package. Designed for low-power operation and a wide supply-voltage range, the LM324 is a go-to choice for students, hobbyists and professional circuit designers working on analog signal processing and general-purpose amplification.

Key Features of the LM324 Quad Op-Amp

• Four independent operational amplifiers in one DIP package for compact designs
• Internally frequency-compensated for stable operation over a wide range of configurations
• Wide operating voltage range: 3V to 32V (single supply) or ±1.5V to ±16V (dual supply)
• Low power consumption, making it suitable for battery-powered applications
• High gain with large output voltage swing for effective analog signal processing
• DIP package simplifies prototyping on breadboards and through-hole PCBs
