LM224J

Overview

The LM224J is a quad operational amplifier manufactured by Texas Instruments, belonging to the LinCMOS series. It features four independent amplifiers within a single package, housed in a 14-CDIP (0.300 inch) through-hole ceramic dual in-line package. The device operates on a supply voltage range of 3 V to 32 V or ±1.5 V to ±16 V. Key electrical parameters include a gain-bandwidth product of 1 MHz, a slew rate of 500 mV/µs, and an input bias current of 45 nA. It supports a maximum output current of 40 mA per channel and functions within a temperature range of -25°C to +85°C.

Feature Summary

• Integrates four independent high-gain operational amplifiers into a single low-power package.
• Utilizes LinCMOS technology to achieve low power consumption while maintaining stable performance.
• Supports operation from a single power supply or split supplies with wide voltage tolerance.
• Features rail-to-rail input capability for extended common-mode voltage range.

Applications

• General-purpose analog signal processing circuits
• Transducer interfaces and buffer stages
• DC gain blocks in instrumentation systems

Procurement Notes

Verify the specific suffix J indicates the ceramic DIP package variant when sourcing. Confirm RoHS compliance status as it may vary by production batch. Ensure the supplier provides official datasheets matching the LM224J designation to avoid confusion with plastic DIP or SOIC variants. Check for lead-free certification if required by assembly standards.

Selection Notes

Select this component when a quad amplifier configuration is required in a through-hole ceramic package. It is suitable for applications needing moderate bandwidth and low power dissipation. Compare against plastic DIP versions if cost or volume packaging is a priority. Consider the input bias current and offset voltage specifications relative to the precision requirements of the target circuit design.

Part Context

This part belongs to the LMx24 family of low-power quad operational amplifiers produced by Texas Instruments. The LM224J specifically denotes the military or industrial grade version packaged in a 14-pin ceramic dual in-line format. It shares functional similarities with the LM124 and LM324 but differs in operating temperature ranges and package materials.
