quad opera t ional amplifier lm324 d e s c r i p t i o n outline drawing the lm324 consist of four independent, high gain, internally frequency com p ensated operational am plifiers which were designed specifically to operate from a single power supply over a wide voltage range. operation from split power supplies is also possible and the low power supply current drain is independent of the m a gnitude of the power supply voltage. application areas include transducer dip14 am plifier, dc gain blocks and all the conventional op am p circuits which now can be easily im plem ented in single power supply sy stem s. fea t ure lar g e dc voltage gain: 100db w i de power supply range: vcc=3v~32v(or vcc= 1.5v~ 1 6 v ) s o p 1 4 input com m on-m ode voltage range includes ground. lar g e output voltage swing :0v~vcc-1.5v power drain suitable for battery operation internally frequency com p ensated for unity gain w i de bandwidth(unity gain) 1mhz v e ry low supply current drain(700a)?essentially independent of supply voltage low input biasing current 45na low input of fset voltage 2m v and of fset current 5na dif f erential input voltage range equal to the power supply voltage com p atible with all form s of logic tiger electronic co.,ltd
