- High common-mode rejection ratio of 80dB (min 65dB), ensuring accurate signal amplification in noisy environments
- Ultra-low input bias current of 0.25µA at 25°C (max 0.5µA), ideal for high-impedance sensor interfaces
- Voltage-feedback architecture with built-in frequency compensation for stable operation across a wide range of gains
- RoHS-compliant (Pb-free) with long product lifecycle (introduced 1989, YTEOL: 15 years), ensuring supply continuity
Applications
The LM324NSR is widely used in signal conditioning circuits for sensors, transducers, and data acquisition systems where low input bias current and high CMRR are critical. Its quad op-amp configuration makes it ideal for active filters, comparators, and instrumentation amplifiers in industrial and consumer electronics. The compact SOP package suits space-constrained PCB designs in automotive, medical monitoring, and general-purpose analog processing applications.
