Overview
The LM158H/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, as well as from split power supplies. This device is particularly useful in systems where simplicity and low power consumption are crucial. The LM158H/NOPB features two independent, high-gain, internally frequency-compensated operational amplifiers, making it suitable for various applications including transducer amplifiers, DC gain blocks, and conventional op-amp circuits in single power supply systems.
