The LM324AMX\/NOPB from Texas Instruments is a quad general-purpose operational amplifier in a 14-pin SOIC package. It operates from a single supply of 3 V to 32 V or dual supplies of \u00b11.5 V to \u00b116 V, with a unity-gain bandwidth of 1 MHz. The device features very low supply current drain (700 \u00b5A total), input common-mode voltage range that includes ground, and is specifically designed for single-supply applications.<\/p>\n

It consists of four independent high-gain internally frequency-compensated amplifiers designed to operate from a single power supply over a wide voltage range. A key differentiator is the input common-mode voltage range that includes ground, allowing the device to operate directly from 5 V logic supplies without requiring negative supplies. The very low supply current of 700 \u00b5A makes it ideal for battery-operated applications. The A suffix indicates tighter specifications for input offset voltage and offset current.","working_principle":"Each of the four amplifier channels in the LM324AMX\/NOPB uses a PNP differential input pair that allows the common-mode input range to extend to ground, enabling true single-supply operation. The input stage feeds a high-gain intermediate stage with internal compensation capacitors for unity-gain stability. The output stage is a class AB configuration that can swing to within 1.5 V of the positive rail and essentially to ground, providing maximum output dynamic range in single-supply configurations. All four amplifiers share common supply rails but operate independently. The 700 \u00b5A total quiescent current is essentially independent of supply voltage magnitude.","pin_description":"
