Overview
The LM358DMR2 is a single supply dual operational amplifier produced by onsemi. It is part of the LM358 series, which is known for its low power drain, wide common-mode input voltage range that includes ground, and the ability to operate on single or split supplies. This makes the LM358DMR2 highly versatile for various applications, especially in single supply configurations. The device is internally compensated and consists of two two-stage operational amplifiers, similar to half of the LM324 quad operational amplifier.
