LPV7215
580 nA Rail-to-Rail Input and Output, 1.8V, Push-Pull
Output Comparator
General Description
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, the LPV7215, with guaranteed operation
at 1.8V, 2.7V and 5.0V, is ideal for use in a variety of
battery-powered 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.
With an operating temperature range of −40˚C to 125˚C, this
comparator can be adopted for extreme temperature appli-
cations. 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 Na-
tional’s advanced VIP50 process.
