The OCE TID-ADC is a Total Irradiation Dose (TID) monitoring module with a high frequency analogue-to-digital converter supporting 8-channel 16-bit successive-approximation-registers. The module is packaged in a SOP-80 high reliability three-dimensional stack System-in-Package (SiP). The TID measurement operates up to 100 kRad cumulative dose providing monitoring throughout the entire service life of the host system in harsh and ionizing environments.
Flexible design allows independent operation of TID monitoring module and SAR ADC. The main product features are:
