7805ALP 16-Bit Latchup Protected ADC

Discontinued Product. Please contact the factory for the latest replacement.


Part Number(s): 7805ALP

DDC’s 7805ALP high-speed analog-to-digital converter features a greater than 50 krad (Si) total dose tolerance, depending upon space mission. Using Mawell’s radiation-hardened RAD-PAK® packaging technology, the 7805ALP incorporates the commercial ADS7805 from Burr Brown. This device is latchup protected by DDC’s LPT™ technology. The 7805ALP, 16-bit sampling CMOS A/D . The device contains a complete 16-bit capacitor-based SAR A/D with S/H, reference, clock, interface for microprocessor use, and three-state output drivers. The 7805ALP is specified at a 100 kHz sampling rate, and guaranteed over the full temperature range. Laser-trimmed scaling resistors provide an industry-standard ± 10V input range, while the innovative design allows operation from a single 5V supply, with power dissipation of under 132 mW.

DDC’s 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 50 krad (Si) radiation dose tolerance. This product is available with screening up to DDC’s self-defiened Class K.
