About
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. It features radiation monitoring based on a dual RADFET cumulative TID detector with a monitoring range up to 100 Krad(Si), and an eight-channel 16-bit precision ADC. The analog to digital conversion performances include a maximum sampling of 1MSPS, analog channel input impedance of 1 MΩ, and a wide input/output port operating voltage range of 1.71 V to 5.25 V (VDRIVE). Each analog input channel can be programmed with dual bandwidth: 25 kHz or 250 kHz, and has ± 20 V clamp protection and 6 kV ESD protection. It also includes flexible and configurable data filter settings, with an oversampling rate of up to 256. Each channel has system phase, offset, and gain calibration functions, and is equipped with analogue input open circuit detection, self-diagnosis and monitoring functions. Data communication includes a CRC error checking function. The product is available in Engineering Models, Industrial Grade, and Aerospace Grade.
