Overview
The LM358TPX/NOPB is a low-power, dual-operational amplifier produced by Texas Instruments. This component is part of the LM158 series, designed to operate from a single power supply over a wide range of voltages, as well as from split power supplies. The LM358 is particularly useful in applications where space is limited due to its availability in a compact 8-bump DSBGA chip-sized package. It is ideal for various electronic systems requiring high gain, low power consumption, and the ability to operate near ground potential.
