APDS-9702

Signal Conditioning IC for Optical Proximity Sensors with Digital I²C Interface

Avago Technologies US Inc.

APDS-9702 is a signal conditioning IC that enhances the performance and robustness of the optical sensors used for proximity or object detection. APDS-9702 is a single chip solution that consists of an I²C Write function, oscillation circuit, LED driver circuit and sunlight cancellation circuit integrated into a single chip. APDS-9702 has artificial light immunity and is also operational under the sun. Design flexibility is optimized as APDS-9702 can be paired up with an integrated proximity sensor or discrete pair solution.

Product Description

APDS-9702 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. APDS-9702 also provides user options in frequency, suitable burst rate, comparator threshold setting and burst off period that can reduce power consumption. These low power consumption features makes it also ideal for low power mobile and handheld devices. APDS-9702 is capable of operating at voltage supply ranging from 2.4 V to 3.6 V. APDS-9702 has two separate output pins for analog and digital outputs. This provides flexibility to use either the analog or digital output (or both) depending on the requirements of the application.
