Overview
The LM358WST, 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 op-amps. It is particularly suited for applications where low power consumption and single-supply operation are crucial. The LM358WST can be directly supplied with standard voltages such as +5 V, making it compatible with logic systems and facilitating the implementation of interface electronics without additional power supplies.
