Description

The 7820 is a microprocessor compatible 8-bit Analog-to-Digital Converter with a 0V to +5V input supply range with a single +5 Volt supply. The 7820 incorporates internal sample-and-hold circuitry which eliminates the need for an external S/H for signals with slew rates less than 100 mV/µs.

The 7820 was designed to be easily interfaced with microprocessors, appearing as either a memory location or I/O port without the need for external interfacing. All outputs are latched and tri-state buffered.

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.
