  The LPV7215 is an ultra low-power comparator with a typical power supply current of 580 nA. It has the best-in-class power supply current versus propagation delay performance available among National's low-power comparators. The propagation delay is as low as 4.5 microseconds with 100 mV overdrive at 1.8V supply.
  Designed to operate over a wide range of supply voltages,from 1.8V to 5.5V, with guaranteed operation at 1.8V, 2.7V and 5.0V, the LPV7215 is ideal for use in a variety of batterypowered applications. With rail-to-rail common mode voltage range, the LPV7215 is well suited for single-supply operation.
  Featuring a push-pull output stage, the LPV7215 allows for operation with absolute minimum power consumption when driving any capacitive or resistive load.
  Available in a choice of space-saving packages, the LPV7215 is ideal for use in handheld electronics and mobile phone applications.The LPV7215 is manufactured with National's advanced VIP50 process.
