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 anddifferentiallinearity 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.
