Description

The MAX9040AEUK-T and MAX9050MAX9053 fea-ture combinations of low-power comparators and a pre-cision voltage reference. Their operating voltage rangemakes them ideal for both +3V and +5V systems. The MAX9040AEUK-T/MAX9041/MAX9050/MAX9051 have a single comparator and reference consuming only 40µA of supply current. The MAX9042/MAX9043/MAX9052/ MAX9053 have dual comparators and a reference,while consuming only 55µA of supply current. Low-volt-age operation and low supply current make these devices ideal for battery operated systems.The comparators MAX9040AEUK-T feature Rail-to-Rail® inputs and out-puts, with a common-mode input voltage range that extends 250mV beyond the supply rails. Input bias cur-rent is typically 1.0pA, and input offset voltage is typi-cally 0.5mV. Internal hysteresis ensures clean output switching, even with slow-moving input signals. The output stage of MAX9040AEUK-T  features a unique design that limits supply current surges while switching, virtually eliminating sup-ply glitches typical of many other comparators. This design of MAX9040AEUK-T also minimizes overall power consumptionunder dynamic conditions. The comparator outputs have rail-to-rail push-pull output stages that sink and source up to 8mA. The propagation delay is 400ns,even with the low operating supply current.The reference output voltage of MAX9040AEUK-T is set to 2.048V in the MAX9040MAX9043 and to 2.500V in the MAX9050MAX9053. These devices are offered in two grades: an A grade with 0.4 initial accuracy and 6ppm/°C tempco, and a B grade with 1% initial accuracy and 100ppm/°C tempco. The voltage reference of MAX9040AEUK-T features a proprietary curvature-correction circuit and laser- trimmed thin-film resistors. The series-mode references can sink or source up to 500µA of load current.
