APDS-9700-020, Бесконтактный датчик, низкий уровень энергопотребления, Аналоговый, Цифровой, 200 мм, QFN

The APDS-9700-020 is a Signal Conditioning IC that enhances the performance and robustness of the optical sensors used for proximity or object detection. It is a single chip solution that consists of a LED driver circuit, sunlight cancellation and built-in LED stuck high protection circuit integrated into a single chip. It has artificial light immunity and is also operational under the sun. Design flexibility is optimized as this can be paired up with an integrated proximity sensor or discrete pair solution. It can be disabled to maximize power savings and battery life in applications such as portable or battery-operated devices. The LED current of the optical proximity sensors can be configured to different levels using a limiting resistor at the LEDA pin. It also provides user flexibility to control the pulse width with suitable burst rate, duty cycle and frequency that can reduce power consumption.
