The SI1142-A11-GM is an optical sensor integrated circuit (IC) with 25% optical efficiency for ambient light, infrared, and ultraviolet (IR, UV) sensing applications. The IC has a built-in infrared diode and an on-chip operational amplifier for measuring the difference in response to UV and IR. This difference provides high accuracy measurement of ambient light and IR levels. The IC has a low-voltage power supply and built-in low-power operational amplifier with low-noise performance.

The IC contains an array of photodiodes connected in series. Each of these photodiodes has its own peak spectral sensitivity and can pick up a different amount of IR and UV light. The photodiodes are connected to the operational amplifier in a certain configuration, allowing the difference between UV and IR signals to be measured. The IC also contains temperature measuring circuitry and a 7-bit analog-to-digital converter (ADC).

The IC is capable of measuring visible light, infrared and ultraviolet radiation. In order to detect visible light, the IC is equipped with a visible light sensitive photodiode. This photodiode is sensitive to light in the range of 400nm to 700nm. The infrared diode of the IC is sensitive to light in the range of 700nm to 1,500nm. The UV Diode is sensitive to light in the UV-A range of 315nm to 400nm. All of these sensors are connected to an amplifier, allowing for measurement of the differences between the light spectra being measured.

Once the ambient light and the IR levels are measured, the IC is able to make calculations to determine the total radiation intensity and the visible portion of it, as well as the temperature. This information is used to make a comprehensive characterization of the environment. This information can be used for such applications as paleo-environmental reconstruction and culture heritage protection studies.

The device is also capable of compensating for the optical aberrations of the lens while measuring, by adjusting the IR and UV gains of the photodiodes. This is in order to make sure that the measurements adhere to the International Commission on Illumination (CIE) standards.

The SI1142-A11-GM is a low power, cost-effective, high accuracy sensor that can be used in a variety of ambient light, infrared, and ultraviolet sensing applications. The device is capable of measuring visible light, infrared and ultraviolet radiation, and can be used for applications such as paleo-environmental reconstruction and culture heritage protection studies. The device is designed to offer a high level of accuracy, low power consumption, and cost-effectiveness in applications where environmental characterization is needed.
