? . wide gain bandwidth : 1.3mhz . input common-mode voltage range includes ground . large voltage gain : 100db . very low supply current/ampli : 375 m a . low input bias current : 20na . low input offset voltage : 5mv max. (for more accurate applications, use the equivalent parts lm124a-LM224a-lm324a which feature 3mv max) . low input offset current : 2na . 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 operational 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 magni- tude of the power supply voltage. 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 input 4 inve rting input 4 non-inve rting input 3 inve rting input 3 - + - + - + - + output 1 inve rting input 1 output 2 pin connections (top view) order codes part number temperature range package ndp lm124 -55 o c, +125 o c ???
