Uploaded by Patrick

LM358 is a dual operational amplifier featuring two independent high-gain op-amps with internal frequency compensation for unity gain. It supports operation from a single supply or split supplies, with a wide 3V–30V power range and an input common-mode range that includes ground. Electrical characteristics cover input offset and bias currents, voltage gain and output swing limits, common-mode and power-supply rejection, channel separation, and short-circuit behavior. Typical performance plots provide input current, gain versus frequency, and voltage follower/pulse response trends.
