Overview
The LM358AM/NOPB is a dual operational amplifier produced by Texas Instruments. It is part of the LM158 series, designed to operate from a single power supply over a wide range of voltages. This makes it highly versatile for various applications, including those in digital systems where a standard 3.3-V power supply is used. The LM358AM/NOPB features two independent, high-gain, internally frequency-compensated operational amplifiers, eliminating the need for dual supplies and allowing direct sensing near ground and output voltage to swing to ground even with a single power supply.
