7872 General Description
Maxwell Technologies' 7872 high-speed 14-bit ADC microcir-cuit features a greater than 100 krad (Si) total dose tolerance;depending upon orbit. The 7872 consists of a track/hold ampli-fier, successive-approximation ADC, 3V buried Zener refer-ence and versatile interface logic. It features a self-contained,laser- trimmed internal clock, so no external clock timing com-ponents are required. For minimum noise possible, the on-chip clock may be overridden to synchronize the device oper-ation 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 speci-fied for dynamic performance parameters including distortion and signal-to-noise ratio.
Maxwell Technologies' patented RAD-PAK® packaging technol-ogy incorporates radiation shielding in the microcircuit pack-age. 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.
