TheMAX40002–MAX40005 and MAX40012–MAX40015 tiny, single comparators are ideal for a wide variety of portable electronics applications such as cell phones, media players, and notebooks that have extremely tight board space and power constraints. These comparators are offered in both, a miniature 4-bump wafer-level package (WLP) with a 0.73mm x 0.73mm footprint (as small as two 0402 resistors) and a 5-pin SOT23 package.This device family operates with a supply voltage range from 1.7V to 5.5V (either VCCor external VREF), and consumes only 500nA of supply current. These devices have a wide input-voltage range of 0.1V to 5.5V, independent of the supply voltage, and maintain high impedance at the inputs even when powered down (VCCor external VREF= 0V). They also feature internal filtering to provide high RF immunity.The MAX40002–MAX40003 and MAX40012–MAX40013 have open-drain outputs, while the MAX40004–MAX40005 and MAX40014–MAX40015 feature push-pull outputs. The MAX40002/MAX40004 and MAX40012–MAX40014 have noninverting inputs, while the MAX40003/MAX40005 and MAX40013–MAX40015 have inverting inputs (see theSelector Guidefor more information).These devices also come with an internal reference. The reference voltage is preset at the factory and parts are offered with the following voltage options: 0.2V, 0.5V, 0.9V or 1.222V (seeOrdering Informationtable).These devices are fully specified over -40°C to +125°C automotive temperature range.ApplicationsElectronic ToysMobile DevicesNotebook ComputersPortable InstrumentationPortable Medical Devices
