Overview
The LM158AJ, produced by Texas Instruments, is a dual low-power operational amplifier designed for a wide range of applications. This component is part of the LM158 series, which is known for its high gain and internal frequency compensation. The LM158AJ is particularly versatile, operating from either a single power supply (3V to 32V) or dual power supplies (±1.5V to ±16V), making it suitable for various electronic systems, including those in digital environments where a +5V power supply is common.
