nanoPower comparators in 0.5-sq-mm packages
With a suggested-use list that majors on portable and battery-power-constrained applications such as electronic toys, mobile devices, notebook computers, portable instrumentation and portable medical devices, Maxim notes that these parts occupy only the space of two 0402 resistors.
This device family operates with a supply voltage range from 1.7V to 5.5V (either VCC or external VREF), has a 9 µsec propagation delay, and consumes 500 nA 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 (VCC or external VREF = 0V). They also feature internal filtering to provide high RF immunity.
The MAX40002–MAX40003 have open-drain outputs, while the MAX40004–MAX40005 feature push-pull outputs. The MAX40002/MAX40004 have noninverting inputs, while the MAX40003/MAX40005 have inverting inputs.
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, or 1.222V. They are fully specified over -40°C to +125°C automotive temperature range.
