APDS-9120
Integrated Optical Proximity Sensors
Data Sheet
Description
Avago’s APDS-9120 is an integrated optical proximity
sensor that combines built-in signal conditioning and
space-saving packaging technology.
This integrated sensor provides ease of use, as it elimi-
nates design efforts required in implementing external
LED drivers, signal filtering and amplification, sunlight
and ambient light immunity and LED stuck high protec-
tion circuit.
APDS-9120 is designed to be a robust proximity sensor.
It has artificial light immunity and operates in sunlight
exposure. 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 features make it
ideal for low power mobile and handheld devices.
Application Support Information
The Application Engineering Group is available to assist
you with the application design associated with APDS-
9120 module. You can contact them through your local
sales representatives for additional details.
