MGy Radiation Assessment of a Space-Graded Amplifier and ADC

This paper shows a high total dose radiation assessment on a set of space qualified components. Two space graded COTS (Commercial off-the-shelf) components were selected and monitored under 60Co gamma radiation, namely an instrumentation amplifier and a 14 bit analogue-to-digital-converter (ADC). The specifications of these COTS components were monitored on-line with a customized test bed, up-to a total ionizing dose larger than 1 MGy and are presented in this paper.
