Overview
The LM358ADR2GH 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 amplifier is particularly useful in single supply applications and offers several advantages over standard operational amplifier types. The LM358 series is equivalent to one-half of an LM324 and is made using two internally compensated, two-stage operational amplifiers.
