Maxim Integrated Products introduces the MAX9060-MAX9065 ultralow-power, low-voltage comparators. Available in two package options, a miniature 1mm x 1mm UCSP and a 5-pin SOT23, these devices maximize space savings, facilitate the prototyping phase, and increase design flexibility.

The MAX9060-MAX9065 operate from a wide, 0.9V to 5.5V power-supply range, which is particularly useful for low-battery conditions in portable equipment. To maximize battery life, the MAX9060-9061 single comparators consume only 350nA (max) of quiescent current at 5.5V. Featuring the industry's smallest footprint and ultralow power consumption, these comparators are suitable for portable applications in which minimal space and power consumption are critical.

The MAX9060-MAX9065 family includes five variations of single comparators and one window comparator. The MAX9060/MAX9061 feature open-drain outputs and draw their supply current (350nA, max) from an external, 0.9V to 5.5V reference voltage. The MAX9062/MAX9063/MAX9064 offer either a push-pull or an open-drain output, consume only 1.1?A (max) at 5.5V, and include a 0.2V internal reference. The MAX9065 3.0V to 4.2V window comparator features a push-pull output and consumes 1.3?A (max) at 5.5V. All devices feature a 0.3V to 5.5V input common-mode range that is independent of the supply voltage.

The MAX9060-MAX9065 are available in lead- and halide-free, RoHS-compliant, 4-bump UCSP and 5-pin SOT23 packages. They are fully specified over the -40C to +85C extended temperature range. Prices start at 85 cents (1,000-up, FOB U.S.A.).
