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
