Overview
The LM224KAN is a quad operational amplifier from the Texas Instruments LM224 series, housed in a 14-pin SOIC package. It features four independent high-gain frequency-compensated amplifiers designed for single-supply operation ranging from 3 V to 32 V, or dual supplies of ±1.5 V to ±16 V. Key electrical parameters include a gain-bandwidth product of 1.2 MHz, a slew rate of 0.5 V/µs, and an input offset voltage of 5 mV. The device operates within a temperature range of -25°C to +85°C and provides 2-kV ESD protection.
Feature Summary
- Features 2-kV electrostatic discharge (ESD) protection on inputs and outputs.
- Designed specifically for single-supply operation with low supply-current drain independent of voltage magnitude.
- Includes four independent, high-gain, frequency-compensated operational amplifiers.
Applications
- Transducer amplifiers
- DC amplification blocks
- Single-supply operational amplifier circuits
Procurement Notes
Verify the specific suffix 'K' indicates the required 2-kV ESD protection level compared to standard variants. Confirm the 'A' grade meets the necessary input offset voltage specifications for the application. Ensure the SOIC-14 package dimensions align with the PCB footprint requirements. Check RoHS compliance status for the specific manufacturing batch.
Selection Notes
Select this component when high ESD robustness is critical for the interface environment. The wide single-supply range allows direct interfacing with standard digital logic voltages without additional negative rails. Consider the 1.2 MHz bandwidth and 0.5 V/µs slew rate for moderate-speed signal processing tasks requiring low power consumption.
Part Context
This part belongs to the LMx24 family of quad operational amplifiers manufactured by Texas Instruments. The LM224 variant offers extended temperature capabilities compared to commercial grades. The 'K' suffix denotes enhanced ESD protection, distinguishing it from standard LM224 parts. It serves as a general-purpose solution for analog signal conditioning in industrial and consumer electronics.
Replacement Considerations
LM224ADR: Standard quad op amp without specified 2-kV ESD protection. LM224KDR: Equivalent performance with 2-kV ESD protection but different packaging suffix. LM324KADR: Commercial grade version with similar electrical characteristics and ESD protection.
