Overview
The LM158WDT, produced by STMicroelectronics, is a low-power dual operational amplifier. This component consists of two independent, high-gain operational amplifiers (op-amps) that are internally frequency compensated. The LM158WDT is designed to operate from a single power supply over a wide range of voltages, making it versatile for various applications. It features low power consumption, low input bias current, and a wide bandwidth, making it suitable for battery-operated devices and systems requiring low power drain.
