?2011 fairchild semiconductor corporation www.fairchildsemi.com rev. 1.0.4 features ? internally frequency compensated for unity gain ? large dc voltage gain: 100db ? wide power supply range: ka258/ka258a, ka358/ka358a: 3v ~ 32v (or 1.5v~ 16v) ka2904 : 3v~26v (or 1.5v ~ 13v) ? input common mode voltage range includes ground ? large output voltage swing: 0v dc to vcc - 1.5v dc ? power drain suitable for battery operation. description the ka258 series consist of two independent, high gain, internally frequency compensated operational amplifiers which were designed specifically to operate from a single power supply over a wide range of voltage. operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. application 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. 8-dip 8-soic 1 1 internal block diagram - + + - 1 2 3 45 6 7 8 v cc out2 in2 (-) in2 (+) out1 in1 (-) in1 (+) gnd ka258/ka258a, ka358/ka358a, ka2904 dual operational amplifier
