LM224APT

Overview

The LM224APT is a quad low-power operational amplifier manufactured by STMicroelectronics, housed in a TSSOP-14 surface-mount package. It features four independent high-gain amplifiers with internal frequency compensation. The device operates from a single power supply ranging from 3 V to 30 V or split supplies of ±1.5 V to ±15 V. Key electrical parameters include a gain-bandwidth product of 1.3 MHz, a slew rate of 400 mV/µs, and a maximum input offset voltage of 5 mV. Each channel provides an output current of 40 mA with a total operating supply current of 1.5 mA. The component supports a wide temperature range from -40°C to +105°C.

Feature Summary

• Internal frequency compensation ensures stability without external components.
• Low power consumption remains independent of the supply voltage magnitude.
• Input common-mode voltage range includes ground potential.

Applications

• Industrial control systems
• General-purpose analog signal processing
• Battery-powered equipment

Procurement Notes

Verify the specific suffix 'APT' against the manufacturer's official datasheet to confirm the TSSOP-14 packaging and reel/cut-tape delivery format. Ensure the order matches the exact part number for the LM224A series variant. Cross-reference the RoHS compliance status and manufacturing origin with the latest supplier documentation before finalizing procurement.

Selection Notes

Select this component when designing circuits requiring multiple operational amplifiers within a compact surface-mount footprint. It is suitable for applications demanding low quiescent current and operation from a single supply rail. Consider its 1.3 MHz bandwidth and 40 mA output drive capability for moderate-speed signal conditioning tasks where space efficiency is critical.

Part Context

This device belongs to the LM224x family, which consists of four independent high-gain operational amplifiers. The family shares architectural similarities with the LM124 and LM324 series but offers specific performance characteristics tailored for low-power applications. The LM224APT represents the commercial grade version available in a thin-shrink small-outline package.
