Overview
The LM158AH/NOPB is a 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 LM158AH/NOPB features two independent, high-gain, internally frequency-compensated operational amplifiers. It 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 swing to ground. This makes it suitable for various applications, including transducer amplifiers, DC gain blocks, and conventional op-amp circuits in single power supply systems.
