Low-power, low-voltage comparators

3 September 2008 Analogue, Mixed Signal, LSI

Available in two package options, a miniature 1 x 1 mm UCSP and a 5-pin SOT23, the MAX9060-MAX9065 comparators from Maxim operate from a 0,9 V to 5,5 V power-supply range, which is particularly useful for low-battery conditions in portable equipment. To maximise battery life, the devices consume only 350 nA of quiescent current at 5,5 V. The device family includes five variations of single comparators and one window comparator. The 9060/9061 feature open-drain outputs and draw their supply current from an external reference voltage. The 9062/9063/9064 offer either a push-pull or an open-drain output, consume only 1,1 μA at 5,5 V, and include a 0,2 V internal reference. The MAX9065 3,0 V to 4,2 V window comparator features a push-pull output and consumes 1,3 μA at 5,5 V. All devices feature a 0,3 V to 5,5 V input common-mode range that is independent of the supply voltage.
