Overview
The LM358DT 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 over a wide range of voltages. This makes it highly versatile for various applications, including transducer amplifiers, DC gain blocks, and conventional op-amp circuits in single power supply systems.
