Features Wide single supply voltage: 4 VDC to 32 VDC Range or dual supplies: ±2 VDC to ±16 VDC Supply current drain independent of supply voltage Low input biasing current: 30 nA High open-loop gain: 70 dB Wide bandwidth: 2.5 MHz (unity gain) Large output voltage swing: (V+ - 1) Vp-p Internally frequency compensated for unity gain Output short-circuit protection 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.
