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.
