Overview
The LM258DMR2G is a dual operational amplifier (op-amp) produced by onsemi. This device is designed for single supply or split supply operation and features low power drain, making it suitable for a wide range of applications. The LM258 series, of which the LM258DMR2G is a part, is equivalent to one-half of the LM324 quad op-amp. It offers several advantages over standard op-amps, including a common mode input voltage range that extends to the negative supply voltage, eliminating the need for external biasing components in many cases.
