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鈥檚 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 鈭?0藲C to 125藲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鈥檚 advanced VIP50 process.
