LM2900LM3900LM3301 Quad Amplifiers

General Description

The LM2900 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 amplifi-

ers make use of a current mirror to achieve the non-invert-

ing input function Application areas include ac amplifiers

RC active filters low frequency triangle squarewave and

pulse waveform generation circuits tachometers and low

speed high voltage digital logic gates
