TCA965 Window Discriminator

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 comparator K2 (V6) and the lower edge voltage on comparator K1 (V7). With indirect setting of the windo.

Features

q Bipolar IC q q q 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 P-DIP-14-1 Type s TCA 965 B s Not for new design Ordering Code Q67000-A8338 Package P-DIP-14-1 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 e.
