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 I

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).
