Total Ionizing Dose Radiation Test on the Temperature Sensor TMP36 from Analog Devices

TMP36 temperature sensors were irradiated with Co-60 gamma rays up to 35 krad(Si). This temperature sensor will be used as a total ionizing dose sensor in a radiation monitor that will be on board the Spanish Earth observation satellite SEOSAT/INGENIO. Several samples were irradiated at different dose rates while their response was continuously measured. The sensitivity of the TMP36 to the total ionizing dose has been assessed by studying the evolution of the next three metrics: the output voltage, its temperature dependence and the power consumption. It has been observed that the degradation of these parameters increase significantly at doses higher than about 7 krad(Si), independently of the dose rate.
