General description
The AS7331 is a low-power, low noise integrated UV sensor. The three separated UVA, UVB and UVC channels convert optical radiation signals via UV optimized photodiodes to a digital result and realize a continuous or triggered measurement. The irradiance responsivity can be adjusted via Gain, conversion time and internal clock frequency to effect sensitivity, full scale range and LSB. The by the AS7331 detected amount of radiation in the set Gain and conversion time configuration will be provided as digital counts by the AS7331. The AS7331 offers a range of 12 Gain steps by a factor of two for each step. The conversion time is internally controlled over a wide range of 15 steps by a factor of two for each step. With the input pin (SYN), the conversion time can be externally controlled to adapt the measurement to the given environment and time base.
