(Si) total dose tolerance, depending upon space mission. The

7672 uses an accurate high-speed DAC and comparator to

achieve conversion time as low as 5 µs while dissipating only

110 mW of power. The 7672 is designed to be used with an

external reference voltage. This allows the user to choose a

reference whose performance suits the application or to drive

multiple 7672s from a single system reference, since the refer-

ence input is buffered and draws very little current. For digital

signal processing applications where absolute accuracy and

temperature coefficients may be unimportant, a low cost refer-

ence can be used. For optimal precision, a high accuracy ref-

erence where an absolute 12-bit accuracy can be obtained

over a wide temperature range may be used. Analog input

range is pin-selectable for 0 to +5V, 0 to +10V, or ±5V, making

the ADC ideal for data acquisition and analog input/output

cards. A high-speed digital interface (125 ns data access time)

with three state data outputs is compatible with most micro-

processors.

Maxwell Technologies' patented R^AD-PAK® packaging technol-

ogy incorporates radiation shielding in the microcircuit pack-

age. 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, R^AD-PAK provides greater than 100

krad (Si) radiation dose tolerance. This product is available

with screening up to Class S.
