APDS-9702
Signal Conditioning IC for Optical Proximity Sensors
with Digital I²C Interface
Data Sheet
Description
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 op-
erational under the sun. Design flexibility is optimized as
APDS-9702 can be paired up with an integrated proximity
sensor or discrete pair solution.
APDS-9702 can be disabled to maximize power savings
and battery life in applications such as portable or bat-
tery-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 consump-
tion 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.
The device is packaged in 8-pin QFN package measuring
0.55mm(H) x 2mm(W) x 2mm(L).
