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 articial light immunity and is also operational

under the sun. Design exibility 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 congured to dierent levels

using a limiting resistor at the LEDA pin. APDS-9700 also

provides user exibility 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 ex-

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).
