Window Discriminator TCA 965 B

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 V_Stab

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.

Functional Description

Amplifier Amp 3 increases the voltage of the reference source R to V_Stab = 2 x V_REF. The amplification factor can be altered by external wiring. With direct setting of the window, the input voltage appears on amplifier Amp 1 (V₈), the upper edge voltage on comparator K2 (V₆) and the lower edge voltage on comparator K1 (V₇).

With indirect setting of the window, the input voltage appears on inputs V₆ and V₇, while the center voltage is connected to amplifier A1 (V₈).

The voltage applied to the input (V₉) of amplifier Amp 2 is subtracted symmetrically from the output voltage of amplifier Amp 1 and added. The comparators switch with hysteresis. The logic gates have open-collector outputs.

If the inhibit input A or B is connected to ground, output A or B will always be high.
