Overview
The LM258D, 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 device consists of two independent, high-gain, internally frequency-compensated op amps. The LM258D is particularly useful in applications where low power consumption and single-supply operation are crucial. It can be directly supplied with standard voltages such as 5 V, making it suitable for integration with logic systems without the need for additional power supplies.
