ZOPT3100 Feature Sheet Revision 1.01

ZOPT3100
Digital RGB/Ambient Light + Proximity Sensor IC
Brief Description
ALS Features
The ZOPT3100 Sensor IC integrates an ambient
light sensor (ALS), a color sensor (CS), and a proximity sensor (PS), as well as an LED driver on a
single chip. The device is connected by an I²C™*
interface to a microcontroller. Other I²C™ or SMBus
devices can be connected to the same interface.
The device has a programmable interrupt with
hysteresis to respond to events and reduce the
microcontroller tasks.

Dynamic range : 0.006 lux to 32,000 lux
ALS measurement uses CS green filtered values
Temperature compensation
CS/ALS output resolution: 14 to 18 bits
Linear output code
50ms conversion rate for 14-bit resolution
50Hz/60Hz light flicker immunity
Fluorescent light flicker immunity

The device allows adjusting the brightness as well
as the color of the display panel. This device can
also measure distance in parallel with ALS and CS
measurements in order to deactivate the touch
screen during phone calls.


5 integrated photodiodes (1 proximity diode and
4 diodes for white, green, blue, and red channels)
5 analog-to-digital converters (ADCs) to measure
PS in parallel to ALS/CS
I²C™ capable of standard mode (100kHz) or fast
mode (400kHz) communication; 1.8V logic
compatible
Programmable interrupt function for ALS (green
channel) and PS with upper and lower thresholds
PS measurement parallel to ALS/CS measurements
Many measurement modes: PS+ALS+CS,
ALS+CS, PS+ALS, PS only, ALS only, CS only
