GENERAL DESCRIPTION
FGD-04D is a digital radiation sensor based in FGDOS® principle. The IC senses and records the accumulated ionizing radiation dose, even when there is no power supply (zero-power sensor). The IC needs to be powered-up only during dose reading, providing truly passive dosimetry with instant read-out capability.
FGD-04D is an I2C slave with 8-bit dose-to-digital converter. The accumulated dose can be read in 8-bit format through standard I2C interface. An analog mode is also supported, the IC is configured as simple plug&play analog sensor, and dose information is provided as analog output voltage.
The IC also incorporates a temperature sensor for temperature dependency correction via post-processing.
