Description

Maxwell Technologies’ 7809LP high-speed 16-bit analog to digital converter features a greater than 100 kilorad (Si) total dose tolerance depending upon space mission. Using Maxwell’s radiation-hardened RAD-PAK® packaging technology, the 7809LP has the same footprint as ADS7809 and is latchup protected by Maxwell Technologies’ Latchup Protection Technology (LPTTM). It is a 24 pin, 16-bit sampling analog-to-digital converter using state-of-the-art CMOS structures.

The 7809LP contains a 16-bit capacitor based SAR A/D with S/H, reference, clock, interface for microprocessor use, and serial output drivers. The 7809LP is specified at a 100kHz sampling rate, and guaranteed over the full temperature range. Laser trimmed scaling resistors provide various input ranges include ±10 V and 0 to 5 V, while the innovative design allows operation from a single +5 V supply, with power dissipation of under 132 mW.

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 K.
