Overview
The LM158N, produced by STMicroelectronics, is a low-power dual operational amplifier designed to operate from a single power supply over a wide range of voltages. This component consists of two independent, high-gain, internally frequency-compensated operational amplifiers. It is particularly suited for applications requiring low power consumption and the ability to operate from a single supply voltage, making it ideal for battery-powered devices and systems where power efficiency is crucial.
