LPV7215

580 nA Rail-to-Rail Input and Output, 1.8V, Push-Pull

Output Comparator

General Description

Features

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.

(Typical unless otherwise noted)

n Push-Pull output current drive

n Temperature range

n Rail-to-rail input

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.

n Tiny SOT23-5 and SC70-5 packages

Applications

n Laptop computers

n Mobile phones

Featuring a push-pull output stage, the LPV7215 allows for

operation with absolute minimum power consumption when

driving any capacitive or resistive load.

n RC timers

n Alarm and monitoring circuits

n Window comparators

n Multivibrators

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.
