The LM3900 series consists of four independent, dual input, internally compensated amplifiers which were designed specifically to operate off of a single power supply voltage and to provide a large output voltage swing. These amplifiers make use of a current mirror to achieve the non-inverting input function. Application areas include ac amplifiers, RC active filters, low-frequency triangle, square wave, and pulse waveform generation circuits, tachometers, and low speed, high voltage digital logic gates.
