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.

Features:-

• Two window settings 

   — direct setting of lower and upper edge voltage (window edges) 

   — indirect setting by window center voltage and half window width 

• Adjustable hysteresis 

• Digital outputs with open collectors for currents up to 50 mA 

• Adjustable reference voltage Vstab
