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
■Noteboo ks and PDA s
■PCMCIA cards
■Cellulars and mobile commu nicat ion
■Alarm and se curity system s
■Replacement of amplifiers used in
comparator configuration with better
performances
