TS7211
SINGLE BiCMOS RAIL TO RAIL
µPOWER COMPARATOR
■ RAIL TO RAIL INPUTS
■ PUSH-PULL OUTPUT
■ SUPPLY OPERATION FROM 2.7V TO 10V
■ TYPICAL SUPPLY CURRENT: 6µA @ 5V
■ RESPONSE TIME OF 0. 5µs AT 5V
■ LOW INPUT CURRENT
■ ESD PROTECTION : 2KV (HBM) 2 00V (MM)
■ AVAILABLE IN TINY SOT23-5 PACKAGE
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
