APDS-9700
Signal Conditioning IC for Optical Proximity Sensors
Data Sheet
Description
APDS-9700 is a signal conditioning IC that enhances the
performance and robustness of the optical sensors used
for proximity or object detection.
APDS-9700 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. APDS-
9700 has artificial light immunity and is also operational
under the sun. Design flexibility is optimized as APDS-
9700 can be paired up with an integrated proximity sen-
sor or discrete pair solution.
APDS-9700 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-9700 also
provides user flexibility to control the pulse width with
suitable burst rate, duty cycle and frequency that can re-
duce power consumption. These low power consump-
tion features makes it also ideal for low power mobile and
handheld devices.
APDS-9700 is capable of operating at voltage supply rang-
ing from 2.4 V to 3.6 V. APDS-9700 has two separate out-
put pins for analog and digital outputs. This provides flex-
ibility 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).
