CM339 l ow p ower q uad v oltage c omparators 2001/07/02 preliminary champion microelectronic corporation page 1 general description features this device consists of four independent precision voltage comparators with an offset voltage specification as low as 2mv max for CM339. all these comparators were designed specifically to operate from a single power supply over a wide range of voltages. operation from split power supplies is also possible. these comparators also have a unique characteristic in that the input common mode voltage range includes ground even though operated from a single power supply voltage. wide single supply voltage range or dual supplies for all devices: +2v to +36v or 1v to 18v very low supply current 1.1ma independent of supply voltage 1.4mw/comparator +5v low input bias current: 25na typ low input offset current: 5na typ low input offset voltage: 1mv typ input common-mode voltage range includes ground low output saturation voltage : 250mv typ, io = 4ma differential input voltage range equal to the supply voltage ttl, dtl, ecl, mos, cmos compatible output symbol pin configuration 14 pin pdip/sop (top view) 1 2 3 4 5 6 7 14 13 12 11 10 9 8 1out 2out vcc 2in- 2in+ 1in- 1in+ 3out 4out gnd 4in+ 4in- 3in+ 3in-
