OCE New ADC SIP Also Measures Accumulated Radiation

The OCE TID-ADC16 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:

  • Radiation monitoring based on dual RADFET cumulative TID detector with monitoring range up to 100 Krad(Si).
  • Eight-channel 16-bit precision ADC.
  • Analog to digital conversion performances:
    • Maximum sampling 1MSPS;
    • Analog channel input impedance: 1 MΩ;
    • Wide input/output port operating voltage range: 1.71 V to 5.25 V (VDRIVE);
  • Voltage input range for each analog channel:
    • Bipolar single ended: ±12.5V, ±10V, ±6.25V, ±5V, ±2.5V
    • Unipolar single ended: 0 to 12.5V, 0 to 10V, 0 to 5V
    • Bipolar differential: ±20 V, ±12.5 V, ±10 V, ±5 V
  • Each analog input channel can be programmed with dual bandwidth: 25 kHz or 250 kHz
