The LM324N is a quad operational amplifier manufactured by Texas Instruments (also available from onsemi and others). It consists of four independent high-gain internally frequency-compensated op-amps designed for single-supply operation from 3V to 32V. The device features low supply current drain, input common-mode voltage range including ground, and large output voltage swing, making it one of the most widely used general-purpose op-amps.<\/p>\n

Designed for single-supply operation from 3V to 32V, it eliminates the need for dual power supplies in many applications. The input common-mode voltage range includes ground, and the output can swing to ground, enabling direct use in 5V digital systems. Low supply current of 700uA (all four amplifiers) makes it suitable for battery-powered designs.","working_principle":"The LM324N contains four independent op-amps, each with a differential input stage, gain stages, and a class AB output stage. Internal frequency compensation provides stability at unity gain without external components. The input stage uses a Darlington configuration for low input bias current. The output stage features a current-sinking capability that allows the output to swing to ground without a pull-down resistor. Each amplifier operates independently with its own inverting input, non-inverting input, and output, sharing only the supply voltage connections.","pin_description":"
