Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at
www.onsemi.com.
Please
email any questions regarding the system integration to

FLD00060
I
2
C Digital Ambient Light and Proximity Sensor
with Built-in IR LED
Features
Built-in temperature compensation circuit
Operating temperature: -30°C to 70°C
Description
The FLD00060 is a digital-output light and proximity
sensor with a two-wire, I
2
C serial interface. It combines
two photodiodes with signal processing on a single
CMOS integrated circuit to provide a linear response
over an effective 16-bit dynamic range from virtually
0 Lux to 64,000 Lux.
A built in proximity sensor provides a measurement of
reflected IR light that results from the proximity of an
object.
The FLD00060 includes an interrupt mode that signals to
the controller readings exceeding a maximum threshold.
Supply voltage range: 2.4V to 3.6V
I
2
C serial port communication: Fast 400kHz
Light sensing
– Full dynamic range: 0.01 Lux to 64,000 Lux
– High resolution range: 0.01 Lux to 320 Lux
– 16-bit effective resolution
– 50Hz/60Hz rejection
– Immunity to IR and UV light
Proximity sensing
– Built-in LED driver, emitter and detector
– Programmable LED drive current
– 11-bit effective resolution
– High ambient light rejection
Size: 3.94mm(L) x 2.36mm(W) x 1.35mm(H)

Absolute Maximum Ratings
(T
A
= 25°C)
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.
