The LM224N from Texas Instruments is a military-grade quad operational amplifier in a 14-pin DIP package, featuring a wide supply range of 3 V to 32 V (or +\/-1.5 V to +\/-16 V), 1.2 MHz gain bandwidth, and operation from -25\u00b0C to +85\u00b0C. Each amplifier draws only 700 \u00b5A total supply current and provides true differential inputs with a common-mode range that includes ground.<\/p>\n

It consists of four independent, high-gain, internally compensated operational amplifiers designed to operate from a single supply over a wide range of 3 V to 32 V, or from dual supplies of +\/-1.5 V to +\/-16 V. Each amplifier features true differential inputs with a common-mode voltage range that includes ground, enabling true single-supply operation without external biasing. The output voltage can swing to ground while operating from a single positive supply. The total supply current for all four amplifiers is only 700 \u00b5A at 5 V and is essentially independent of the supply voltage magnitude. With 1.2 MHz gain bandwidth, 0.5 V\/\u00b5s slew rate, and 100 dB large-signal voltage gain, the LM224N is suitable for a wide range of general-purpose amplification, filtering, and signal conditioning tasks. The PDIP-14 through-hole package enables easy prototyping and field service.","working_principle":"The LM224N uses a PNP input stage that allows the input common-mode voltage range to extend to ground (0 V) in single-supply operation. The PNP input transistors draw bias current out of the input pins (nominally 45 nA), which flows through external source resistance. Each amplifier consists of a differential input stage, a high-gain intermediate stage, and a Class AB output stage capable of sourcing 20 mA and sinking 10 mA. Internal compensation capacitors provide unity-gain stability without external components. The output stage includes active current limiting and can drive capacitive loads directly. In single-supply operation, the output transistor can pull down to within a few millivolts of ground, but cannot pull all the way to V+. The 1.2 MHz gain bandwidth product and 0.5 V\/\u00b5s slew rate are set by the internal compensation capacitor and the input stage tail current, respectively.","pin_description":"
