1/13 n wide gain bandwidth : 1.3mhz n input common-mode voltage range includes ground 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 : 5mv max. (for more accurate applications, use the equiv- alent parts lm124a-lm224a-lm324a which feature 3mv max.) n low input offset current : 2na n wide power supply range : single supply : +3v to +30v dual supplies : 1.5v to 15v 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. 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 lm124 -55c, +125c lm224 -40c, +105c lm324 0c, +70c example : lm224n n dip14 (plastic package ) d so14 (plastic micropackage ) p tssop14 (thin shrink small outline package) inverting input 2 non-inverting input 2 non-inverting 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-inverting input 4 inverting input 4 non-inverting input 3 inverting input 3 - + - + - + - + output 1 inverting input 1 output 2 lm124 lm224 - lm324 low power quad operational amplifiers december 2001
