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 mak es 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

1) Maximum values include unavoidable inaccurates of the industrial test.

2) Design evaluation.

3) Limits are 100% production tested at +25°C. Limits over temperature are guaranteed through correlation and by design.
