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 onchip clock may be overridden to synchronize the device operation to the digital system.
The 7872 is a serial output device. It is capable of interfacing to all modern microprocessors and digital signal processors. The 7872 operates from ±5V power supplies, accepts bipolar input signals of ±3V and is able to convert full power signals up to 41.5 kHz. It is also fully specified for dynamic performance parameters including distortion and signal-to-noise ratio.
About RAD-PAK® Technology
Maxwell Technologies' patented RAD-PAK® packaging technology incorporates radiation shielding in the microcircuit package. It eliminates the need for box shielding while providing the required radiation shielding for a lifetime in orbit or space mission. In a GEO orbit, RAD-PAK provides greater than 100 krad (Si) radiation dose tolerance. This product is available with screening up to Class S.
