LM358 dual op-amp IC — DIP-8, single supply 3V–32V, wide voltage, amplifier and comparator NY-D01 this voltage sensor module offersThe LM358 is one of the most widely used dual operational amplifier (op amp) ICs, available here in the classic DIP 8 through hole package. It contains two independent, high gain, internally frequency compensated op amps designed to operate from a single power supply over a wide voltage range of 3V to 32V (or 1. 5V to 16V split supply). Its low supply current drain, independent of supply voltage magnitude, makes it ideal for battery powered and low
