Overview
The LM358NG, produced by onsemi, is a dual operational amplifier that leverages the circuit designs developed for quad operational amplifiers. This device is notable for its low power drain, extended common mode input voltage range that includes ground/VEE, and the capability for single supply or split supply operation. The LM358 series is functionally equivalent to one-half of the LM324 and offers several advantages in single supply applications, including operation at supply voltages ranging from 3.0 V to 32 V and reduced quiescent currents compared to other operational amplifiers like the MC1741.
