The LM324 series are low-cost, quad operational amplifiers with true differential inputs.
They have several advantages over standard operational amplifier types in single supply applications, including the ability to operate at supply voltages as low as 3.0 V or as high as 32 V with low quiescent currents.
The common-mode input range includes the negative supply, eliminating the need for external biasing components in many applications.
The output voltage range also includes the negative power supply voltage.
The devices are short-circuited protected and internally compensated, with industry standard pinouts.
They are also ESD clamped on the inputs to increase ruggedness without affecting device operation.
The LM324 series is Pb-free, halogen-free/BFR-free, and RoHS compliant.
The devices are qualified for automotive use and have maximum ratings and electrical characteristics specified in the datasheet.
The circuit description includes a representative circuit diagram and large signal voltage follower response, as well as information on the input and output voltage limits, power supply current, and gain and phase margin.
