Overview
The LM158H, produced by Texas Instruments, is part of the LM158 series of operational amplifiers. These devices consist of two independent, high-gain, internally frequency-compensated operational amplifiers designed to operate from a single power supply over a wide range of voltages. They can also operate from split power supplies. The LM158H is particularly notable for its low power supply current drain, which is essentially independent of the supply voltage, making it suitable for battery operation and other low-power applications.
