The TSL25711FN is an integrated, narrow-spectrum, ambient light and IR sensing light-to-digital converter. This device is specifically designed to measure the intensity of light from a variety of different sources. It is ideal for use in a wide range of applications including automotive, industrial, consumer, security and medical market segments.

The TSL25711FN is built with specialized optics to filter out interference from other light sources, maximizing performance while minimizing noise and power consumption. It also includes a high-accuracy, integrated 16-bit analog-to-digital converter and I2C-compatible digital interface. This allows the device to operate at low power and in various environmental conditions.

The TSL25711FN’s application field is broad, making it useful for a variety of purposes including human-machine interface (HMI) systems, mobile devices, automated lighting control, and motion sensing applications. It is specifically designed to measure visible light and near infrared (IR) radiation with a peak sensitivity of 850nm.

The device’s operating principle is that it uses high performance optics and filters to transmit light of only one wavelength to the 10-bit AR-correction filter. The filter transfers the received data to the integrated 16-bit ADC, where it is digitized and sent out through the I2C bus for further data processing.

The filters employed by the TSL25711FN offer a wide spectrum of visible and IR light wavelengths, allowing the device to measure the intensity of multiple light sources simultaneously. It is equipped with an integrated one- and two-dimensional photo sensor, allowing it to detect the angular relationships of the measured light intensities.

The device also offers a two-pole high-pass filter, which further helps to eliminate the influence of infra red radiation (IRR) and other environmental noise factors. Additional features include a built-in temperature compensation that allows for more accurate measurements in different environments, and a dynamic current-mode control for improved power efficiency.

The TSL25711FN’s performance is the result of careful design and optimization. The device provides a fast response time, high sensitivity, low power consumption, and reliable measurements in a wide range of conditions. This makes it suitable for a variety of applications in the consumer, automotive, industrial, medical, security, and other markets.
