1/13 n wide gain bandwidth : 1.3mhz n large voltage gain : 100db n very low supply current/ampli : 375 m a n low input bias current : 20na n low input offset voltage : 3mv max. n low input offset current : 2na n wide power supply range : single supply : +3v to +30v dual supplies : 1.5v to 15v n input common-mode voltage range includes ground n esd internal protection : 2kv description these circuits consist of four independent, high gain, internally frequency compensated operation- al amplifiers. they operate from a single power supply over a wide range of voltages. 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. all the pins are protected against electrostatic dis- charges up to 2000v (as a consequence, the input voltages must not exceed the magnitude of v cc + or v cc - .) order code n= dual in line package (dip) d= small outline package (so) - also available in tape & reel (dt) p= thin shrink small outline package (tssop) - only available in tape &reel (pt) pin connections (top view) part number temperature range package nd p lm124a -55 c, +125 c ??? lm224a -40 c, +105 c ??? lm324a 0 c, +70 c ??? example : lm224an n dip14 (plastic package) d so14 (plastic micropackage) n dip14 (plastic package) p tssop14 (thin shrink small outline package) inve rting input 2 non-inve rting input 2 non-inve rting input 1 cc v - cc v 1 2 3 4 8 5 6 7 9 10 11 12 13 14 + output 3 output 4 non-inve rting i nput 4 inve rting input 4 non-inve rting i nput 3 inve rting input 3 - + - + - + - + output 1 inve rting input 1 output 2 lm124a lm224a - lm324a low power quad operational amplifiers march 2001
