Overview
The LM358AMX, produced by Texas Instruments, is a dual operational amplifier designed for low-power applications. It is part of the LMx58 series, which includes the LM158, LM258, and LM358. This device is particularly notable for its ability to operate from a single power supply voltage, eliminating the need for dual supplies. This makes it highly versatile and suitable for a wide range of applications, including those in digital systems where a standard 3.3-V power supply is used.
