Abstract :
Two different 12-bit analog-to-digital converter technologies, CMOS and BiCMOS, from Burr-Brown were compared for total dose responses. The BiCMOS converter appears to be a better candidate for space applications. CMOS devices showed larger degradation with both high dose rate (HDR) and low dose rate (LDR). An external voltage reference can be used for a radiation hardened process 12-bit converter from Analog Devices to maintain accuracy up to 1 Mrad(Si). DATEL´s 16-bit hybrid converter showed a low failure level with HDR
