Overview
The LM358AWPT is a low-power dual operational amplifier produced by STMicroelectronics. It consists of two independent, high-gain, internally frequency-compensated op amps designed to operate from a single power supply or split supplies over a wide range of voltages. This device is particularly useful in applications where low power consumption and high performance are required.
The LM358AWPT can operate from a single supply voltage ranging from 3 V to 32 V or from dual supplies with a difference of 3 V to 32 V. It is suitable for various applications, including transducer amplifiers, DC gain blocks, and conventional op amp circuits in single-supply systems.
