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 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, squarewave and

pulse waveform generation circuits, tachometers and low

speed, high voltage digital logic gates.
