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.
