?2012 fairchild semiconductor corporation www.fairchildsemi.com rev. 1.0.8 features ? internally frequency compensated for unity gain ? large dc voltage gain: 100db ? wide power supply range: ka324 / ka324a : 3v~32v (or 1.5 ~ 16v) 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 consist of four independent, high gain, internally frequency compensated operational amplifiers which were designed specifica lly 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 am plifier, 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 1 2 3 4 5 6 78 9 10 11 12 13 14 1 2 3 4 + _ + + + _ _ _ out4 gnd out2 out1 out3 in4 (-) in3 (-) in4 (+) in3 (+) in1 (-) in1 (+) in2 (+) in2 (-) v cc ka324/ka324a, ka2902 quad operational amplifier
