GENERAL DESCRIPTION
FGD-03F is a high TID digital radiation sensor based in FGDOS® principle. Sensor output is a frequency modulated pulse train proportional to radiation dose. Internal counters allow radiaton dose digital value to be read via SPI interface.
Chip serial number is provided for sensor tracking. In passive mode, the chip is still sensing the acumulated radiation dose even when there is no power supply. Sensor temperature dependency is internally compensated.
Internal +18V charge pump allows FGDOS® sensor recharging from a single 5V supply. On-chip temperature sensor and reference channel are provided for extended precision applications, via digital post-processing.
