Introduction The LM358 is a dual operational amplifier (op-amp) IC integrated circuit combining two independent, high gain, internally frequency-compensated amplifiers in a single package. It was specifically designed to operate well on a single supply voltage, although it can also be used with dual (±) supplies. Because of its ability to sense voltages near the […]
Introduction The LM324 is a widely used quad operational amplifier (op-amp) IC that integrates four independent, high-gain, internally frequency-compensated amplifiers in a single package. It was designed especially to be useful in single-supply applications, though it can also operate from dual (±) supplies. Because of its ability to handle input voltages that include the negative […]
Introduction The LM339 is a popular quad voltage comparator IC that integrates four independent comparators into a single package. Unlike operational amplifiers, comparators are designed to switch quickly and decisively, producing a digital (binary) output that indicates which of two analog input voltages is higher. The LM339 is optimized for such applications: it can operate […]
