Philips Semiconductors Product specification Low power quad op amps LM124/224/324/324A/ SA534/LM2902 DESCRIPTION The LM124/SA534/LM2902 series consists of four independent, high-gain, internally frequency-compensated operational amplifiers designed specifically to operate from a single power supply over a wide range of voltages. PIN CONFIGURATION D, F, N Packages OUTPUT 1 –INPUT 1 1 2 3 4 5 6 7 –+ 2 +– 3 1 –+ 4 +– 14 13 12 11 10 9 8 OUTPUT 4 –INPUT 4 +INPUT 4 GND +INPUT 3 –INPUT 3 OUTPUT 3 UNIQUE FEATURES In the linear mode, the input common-mode voltage range includes ground and the output voltage can also swing to ground, even though operated from only a single power supply voltage. The unity gain crossover frequency and the input bias current are temperature-compensa [ ... ]
