HS-9008RH
Data Sheet August 1999 File Number 3279.3
Radiation Hardened CMOS 8-Bit Flash Analog-to-Digital Converter
The Intersil HS-9008RH is a CMOS 8-Bit Flash Converter designed for space applications where relatively low power, exceptional accuracy and very fast conversion speeds are a necessity. The HS-9008RH design differs substantially from most other available Flash Converters as it employs fully differential analog input sampling networks and amplifiers, as well as regenerative, offset nulled (error correcting) comparators. These circuit techniques improve noise performance and render the circuit much less sensitive to process and radiation induced device parametric shifts. Outstanding integral and differential linearity error is achieved through the use of a metal film resistor network which exhibits >10-bit linearity without trim. As a result of these innovations, the device operates with a single fixed reference supply as opposed to the multiple, adjustable references used in similar devices. This combination of features makes the HS-9008RH one of the best 8-Bit Flash Converters available in the Commercial, Military or Rad Hard markets. Specifications for Rad Hard QML devices are controlled by the Defense Supply Center in Columbus (DSCC). The SMD numbers listed here must be used when ordering. Detailed Electrical Specifications for these devices are contained in SMD 5962-96696. A "hot-link" is provided on our homepage for downloading. http://www.intersil.com/spacedefense/space.htm
