Overview
The LM224N is a low-power quad operational amplifier from STMicroelectronics, featuring four independent high-gain amplifiers with internal frequency compensation. It supports single-supply operation from 3 V to 30 V or dual supplies of ±1.5 V to ±15 V. Key electrical parameters include a gain-bandwidth product of 1.3 MHz, a slew rate of 0.4 V/µs, and an input bias current of 20 nA. The device offers a large voltage gain of 100 dB and operates within a temperature range of -40°C to +85°C.
Feature Summary
- Internal frequency compensation eliminates the need for external components
- Wide common-mode voltage range includes ground potential
- Low power supply current drain remains independent of supply voltage magnitude
Applications
- Transducer amplifiers
- DC gain blocks
- Integrators
Procurement Notes
Verify the package type matches the required footprint, as the 'N' suffix typically indicates a DIP-14 package. Confirm the specific grade (e.g., commercial vs. industrial) against the datasheet to ensure the operating temperature range meets system requirements. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity and traceability.
Selection Notes
Select this component when a cost-effective, general-purpose quad op-amp is needed for single-supply applications. It is suitable for systems requiring moderate bandwidth and low power consumption. Ensure the load current requirements do not exceed the typical output drive capability specified in the datasheet for the chosen supply voltage.
Part Context
This component belongs to the LM224 series, which consists of four independent operational amplifiers on a single chip. The series is designed for versatile analog signal processing tasks. The LM224 variant specifically targets commercial temperature ranges, offering a balance between performance and power efficiency for general electronic circuits.
Replacement Considerations
Compatible substitutes include the LM324N and TL084CN. Verify pin compatibility and electrical specifications such as slew rate and offset voltage before substitution.
