DESCRIPTION:
Maxwell Technologies’ 7872 high-speed 14-bit ADC microcircuit features a greater than 100 krad (Si) total dose tolerance; depending upon orbit. The 7872 consists of a track/hold amplifier, successive-approximation ADC, 3V buried Zener reference and versatile interface logic. It features a self-contained, laser- trimmed internal clock, so no external clock timing components are required. For minimum noise possible, the on chip clock may be overridden to synchronize the device operation to the digital system. The 7872 is a serial output device.
