Overview
The LM224AD, produced by Texas Instruments, is a quad operational amplifier designed for general-purpose applications. This device features four independent, high-gain operational amplifiers with frequency compensation implemented internally. The LM224AD operates over a wide range of supply voltages from 3 V to 32 V (or ±1.5 V to ±16 V) and is capable of functioning within a temperature range of -25°C to 85°C. Although the LM224AD is currently obsolete and no longer in production, it remains a significant component in many existing designs due to its robust specifications and reliability.
