Description

The TS7221 is a micropower comparator

featuring a 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 2.7-, 5- and 10-V operation

over industrial temperature ranges

(-40°C to +85°C).

The TS7221 features an open-drain output stage.

The speed-to-power ratio makes this device ultra-

versatile for a wide range of applications.
