Maxwell Technologies’ 8408 is a monolithic quad 8-bit multiplying digital-to-analog CMOS converter. Each DAC has its own reference input, feedback resistor, and onboard data latches that feature read/write capability. The readback function serves as memory for those systems requiring self-diagnostics. A common 8-bit TTL/CMOS compatible input port is used to load data into any of the four DAC data-latches. Control lines DS1, DS2 and A/B determine which DAC will accept data.
Data loading is similar to that of a RAMs write cycle. Data can be read back onto the same bus with control line R/W. The 8408 is a bus compatible with most 8-bit microprocessors, including the 6800, 8080, 8085, and Z80. The 8408 operates on a single +5 volt supply and dissipates less than 20 mW. The 8408 is manufactured using highly stable, thin-film resistors on an advanced oxide-isolated, silicon-gate, CMOS process. The improved latch-up resistant design eliminates the need for external protective Schottky diodes.
About RAD-PAK® Technology
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.
