Manufacturer: Description: Pin 16 is the (-) clamp input pin. This pin is the inverting input to the clamp comparator. A 10KΩ feedback resistor is connected from this pin to the output pin of the amplifier (pin 14). When the clamp comparator is enabled, the voltage at pin 16 is compared to the voltage at pin 17, which is the non- inverting input of the clamp comparator. A source or sink cur- rent is generated at pin 10 to charge or discharge the clamp cap and supply DC bias to the video amplifier. The DC voltage at pin 17 is user adjustable through a 100KΩ potentiometer voltage divider to Vref (see Figure 2). In DC coupled cathode drive applications, brightness can be varied by varying the DC voltage at pin 17. |
