7809C 16-Bit Latchup Immune Analog to Digital Converter


Part Number(s): 7809C

DDC’s 7809C 16-bit 100 kSPS analog to digital converter features a greater than 100 krad (Si) total dose tolerance depending upon space mission.

The 7809C contains a 16-bit capacitor based A/D with S/H, reference, clock, interface for microprocessor use, and serial output drivers. The 7809C is specified at a 100kHz sampling rate, and guaranteed over the full temperature range. Each part contains a successive approximation, switched capacitor ADC, an internal 2.5 V reference, and a high speed serial interface. The ADC is factory calibrated to minimize all linearity errors.

DDC's patented RAD-PAK® packaging technology incorporates radiation shielding in the microcircuit package. This technology greatly improves TID tolerance. In a GEO orbit, RAD-PAK® provides greater than 100 krad (Si) radiation dose tolerance. This product is available with screening up to DDC's self-defined Class S.
