Integrated Optical Proximity Sensors

APDS-9120 is an integrated optical proximity sensor that combines built-in signal conditioning and space-saving packaging technology.

This optical proximity sensor provides ease of implementation as it eliminates design efforts required to implement external LED driver, signal filtering and amplification, sunlight and ambient light immunity, LED stuck high protection circuit.

APDS-9120 is designed to be a robust optical proximity sensor. It has artificial light immunity and is also operational under the sun. Both analog and/or digital output options are available.

To maximize power savings and battery life in applications such as portable or battery-operated devices, APDS-9120 has a shutdown mode feature. With an external limiting resistor, the LED current of the optical proximity sensors can be configured to various levels. The pulse width, burst rate, duty cycle and frequency can be controlled to minimize power consumption. These low power consumption features makes it also ideal for low power mobile and handheld device.
