The window discriminator compares an input voltage to a defined voltage window. The

digital outputs show whether the input voltage is below, within or above this window.

The TCA 965 B window discriminator is especially suitable as a tracking or

compensating controller with a dead band in control engineering and for the selection of

DC voltages within a certain tolerance of the required setpoint value in measurement

engineering. When it is used as a Schmitt trigger, switching frequencies up to a typical

value of 50 kHz are possible.
