ITR9907

Optical Sensors - Reflective - Analog Output

Optical sensors are devices designed to detect and measure light or infrared radiation, which is often referred to as optical radiation. They are capable of detecting and measuring the amount of radiation, as well as its intensity or color. Optical sensors are typically used to detect and control the ambient lighting level in environments, as well as to measure the brightness of reflected light.

ITR9907 is a high-performance, reflective analogue-output optical sensor that is designed to detect, measure and control ambient light levels. It is capable of assigning a specific voltage or current value to each point along the absorption spectrum, enabling accurate light intensity measurements in addition to a wide range of illumination applications. The device is also capable of generating a voltage signal that is proportional to reflected light intensity.

The ITR9907 is built on a standard CMOS process, and is particularly suitable for applications that are interested in measuring the intensity of reflected and ambient light. It features an integrated photodiode on the optical sensing region, which is sensitive to the light intensity. The photodiode is connected to the programmable reference voltage, which is then compared with the output voltage to form a current source proportional to the amount of light.

The device also features an adjustable transimpedance amplifier (TIA), which enables the measurement of very small changes in the light intensity, such as detecting darkness and defining light thresholds. The output of the TIA is then amplified and sent to the internal RAM, where it is stored in a digital format. A final amplifier stage converts the digital signal into an analogue voltage output, which is used to provide an accurate representation of the light intensity.

In addition, the ITR9907 includes features such as an integrated temperature sensor, multiple digital and analog input/output pins, an external clock source, and programmable delay. These features ensure that the device can deliver precise and reliable measurements, while also making it easy to integrate the device into existing systems.

The ITR9907 offers high resolution for accurate light readings, and features a wide dynamic range for ambient light levels as low as 0.1 lux and up to 100,000 lux. The device is also available in a wide variety of packaging solutions to meet any application requirements. With the ITR9907, it is possible to accurately measure and control ambient light levels, making it an ideal solution for industrial temperature sensing, medical devices, and other applications that require a reliable optical measurement solution.
