LM224N

Overview

The LM224N is a quad operational amplifier manufactured by onsemi, housed in a 14-pin PDIP package. It features four independent high-gain frequency-compensated amplifiers designed for single-supply operation over a wide voltage range of 3 V to 32 V. Key electrical parameters include a gain-bandwidth product of 1 MHz, a slew rate of 600 mV/us, and an input offset voltage of 5 mV. The device draws 175 uA per channel with a maximum output current of 40 mA. It operates within a temperature range of -25 C to +85 C.

Feature Summary

• True differential input stage allows common-mode input voltage to include the negative supply, eliminating external biasing components.
• Output voltage range includes the negative power supply voltage, facilitating rail-to-rail functionality relative to ground.
• Short-circuit protected outputs enhance device reliability during fault conditions.
• Internal frequency compensation simplifies circuit design by ensuring stability without external components.

Applications

• Transducer amplifiers
• DC amplification blocks
• Single-supply digital system interface electronics

Procurement Notes

Verify component authenticity through authorized distribution channels due to potential availability issues. Confirm RoHS compliance status as indicated in official documentation. Ensure proper handling procedures are followed during installation. Check for specific ordering suffixes that may affect packaging or performance characteristics. Validate datasheet revisions against the manufacturing date code.

Selection Notes

Select this component for applications requiring low-power quad amplification from a single supply. Consider the 1 MHz bandwidth and 600 mV/us slew rate for signal processing needs. Evaluate the 5 mV input offset voltage for precision requirements. Assess the 3 V to 32 V operating range against system power constraints. Verify thermal performance within the specified industrial temperature limits.

Part Context

The LM224N belongs to the LM224 series of low-power quad operational amplifiers. It shares architectural similarities with the LM324 and LM124 but is optimized for specific commercial or industrial temperature ranges. The device integrates four amplifiers into a single package, reducing board space compared to discrete solutions. It serves as a general-purpose solution for analog signal conditioning in cost-sensitive designs.

Replacement Considerations

LM324N: Verify temperature range compatibility as LM324 typically covers a wider commercial range. LM2902N: Confirm voltage specifications align with system requirements. NCV2902: Suitable if automotive-grade qualification is required. Always cross-reference pinouts and electrical parameters before substitution.
