?2000 fairchild semiconductor international www.fairchildsemi.com rev. 5.0 features ? internally frequency compensated for unity gain ? large dc voltage gain: 100db ? wide power supply range: ka224 / ka224a, ka324 / ka324a : 3v~32v (or 1.5 ~ 15v) KA2902: 3v~26v (or 1.5v ~ 13v) ? input common-mode voltage range includes ground ? large output voltage swing: 0v to v cc -1.5v ? power drain suitable for battery operation description the ka324 series consists of four independent, high gain, internally frequency compensated operational amplifiers which were designed specifically to operate from a single power supply over a wide voltage range. operation from split power supplies is also possible so long as the differ- ence between the two supplies is 3 volts to 32 volts. applica- tion areas include transducer amplifier, dc gain blocks and all the conventional op amp circuits which now can be eas- ily implemented in single power supply systems. 14-sop 14-dip 1 1 internal block diagram ka224/ka224a, ka324/ka324a, KA2902 quad operational amplifier
