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. Semiconductor Group 1 This datasheet has been downloaded from http://www.digchip.com at this page 1998-02-10 TCA 965 B Functional Description
Amplifier Amp 3 increases the voltage of the reference source R to VStab = 2 x VREF. 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 …
