Abstract :
The total dose response of the Analog Devices AD590 is presented for a variety of irradiation test conditions. The parts packaged in flat-packs show very large enhanced low dose rate sensitive (ELDRS) response for unbiased irradiation, starting at about 20 krad, whereas parts packaged in TO-52 cans are not ELDRS. The reason for this package sensitivity appears to be a result of hydrogen trapped in the cavity of the flat-pack package. The responses at 10 mrad/s and 3 mrad/s are essentially the same, indicating that the low dose rate enhancement factor has leveled off below 10 mrad/s. Elevated temperature irradiation at 100degC and 5 rad/s does not simulate the low dose rate response.
