Overview
The LM358AWST is a low-power dual operational amplifier produced by STMicroelectronics. It is part of the LM158W, LM258W, and LM358W series, designed to operate from a single power supply over a wide range of voltages. This amplifier is suitable for various applications, including transducer amplifiers, DC gain blocks, and conventional op-amp circuits, particularly in single power supply systems. The LM358AWST can be directly supplied with standard voltages such as +5 V, making it convenient for use in logic systems and interface electronics without the need for additional power supplies.
