LM224 / LM224DR Quad Single-Supply Op-Amp IC – SOP-14, Pack of 5
The LM224 / LM224DR is the SMD surface-mount version of the classic LM324 quad op-amp – four independent single-supply operational amplifiers in a compact SOP-14 package. With single-supply operation from 3V to 32V, input common-mode range extending to ground, and output swing to within millivolts of the negative rail, it's the go-to quad op-amp for battery-powered circuits, sensor signal conditioning, and analog processing in PCB designs. The LM224 is the industrial-temperature version of the LM324 (−40°C to +105°C). This 5-piece SOP-14 pack is ideal for PCB design and production.

LM224 vs LM324 – Temperature Grade
- LM224: Industrial grade – −40°C to +105°C, SOP-14 SMD
- LM324N: Commercial grade – 0°C to +70°C, DIP-14 through-hole
- Functionally identical – same electrical specifications, different temperature range and package
- Choose LM224 for industrial, automotive, or outdoor applications requiring extended temperature range
Typical Applications
- Sensor signal conditioning: 4-channel amplification for temperature, pressure, and current sensors
- Comparator arrays: 4 voltage threshold detectors in one package
- Active filters: Multi-stage low-pass, high-pass, and bandpass filter banks
- Battery-powered circuits: Single-supply analog processing from 3V–5V
- Industrial control: Signal conditioning for PLC analog inputs
- PCB repair: SMD replacement for failed LM224/LM324 in consumer and industrial electronics
