Overview
The LM358H/NOPB is a low-power, dual-operational amplifier produced by Texas Instruments. This device 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 LM358H/NOPB is particularly useful in applications where a single power supply is preferred, eliminating the need for dual supplies and allowing direct sensing near ground and output voltage swings to ground.
The device features two internally compensated operational amplifiers, making it suitable for various applications such as transducer amplifiers, DC gain blocks, and general signal conditioning and amplification.
