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 avail-
able among National's low-power comparators. The propa-
gation 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 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.
Available in a choice of space-saving packages, the LPV7215
is ideal for use in handheld electronics and mobile phone ap-
plications. The LPV7215 is manufactured with National's ad-
vanced VIP50 process.
