DESCRIPTION

The TS7211 is a micropower comparator

featuring rail to rail input performance in a tiny

SOT23-5 package. This comparator is ideally

suited to space and weight critical applications. It

is fully specified at 2.7V, 5V and 10V operations

over the industrial temperature range (-40/+85°C).

The TS7211 features a push-pull output stage.

The speed to power ratio makes this device ultra

versatile for a wide range of applications.

APPLICATIONS

■ Battery powered systems

■ Notebooks and PDAs

■ PCMCIA cards

■ Cellulars and mobile communication

■ Alarm and security systems

■ Replacement of amplifiers used in

comparator configuration with better

performances
