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).
PIN CONNECTIONS (top view)
The TS7211 features a push-pull output stage.
The speed to power ratio makes this device ultra
versatile for a wide range of applications.
