(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.  
FEATURES:  
12-bit high speed A/D converter  
RAD-PAK® radiation-hardened against natural space radia-  
tion  
Total dose hardness:  
- > 100 krad (Si), depending upon space mission

- SEL > 120 Mev/mg/cm2  
- SEUTH > 5.8 Mev/mg/cm2  
- SEUSat = -1E-4 cm2/Device  
Package:  
- 24 pin RAD-PAK® flat package  
- 24 pin RAD-PAK® DIP  
Fast conversion times:  
- 7672-05: 5 µs  
Low 110 mW typical power consumption  
- Corrects all single-bit errors  
- Detects all double and some triple-bit errors  
High-speed BiCMOS technology  
- Choice of +5V and +10V input ranges  
- Operates with +5V and -12V power supplies  
- Fast 125 ns bus-access time  
Maxwell Technologies' patented RAD-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, RAD-PAK provides greater than 100  
krad (Si) radiation dose tolerance. This product is available  
with screening up to Class S.  
DESCRIPTION:  
Maxwell Technologies’ 7672 high-speed 12-bit analog-to-  
digital converter microcircuit features a greater than 100 krad
