AS73210
Integral True Color Sensor
QFN16
Order No.: 305090005
Status: preliminary
INTRODUCTION
The AS73210 is a True Color
1
Sensor IC with a
filter
function
based
on
the
color
standard
CIE 1931/DIN 5033 (human eye perception) in a
compact QFN16 package. The AS73210 is long-
term stable over the entire product lifetime and
resistant
to
external
influences
such
as
temperature or aging drifts, due to the special
JENCOLOR
®
interference filter technology.
The
JENCOLOR
®
sensors
are
made
of
19x3 photodiodes integrated on-chip (special pin
silicon technology with advanced sensitivity). The
diodes are aligned as segments of a multiple-
element hexagonal matrix structure with the
diameter of 2 mm.
The design as Si-PIN photodiodes allows signal
frequencies up to the MHz-range. In order to
achieve
minimal
cross
talk
between
the
photodiodes the individual sectors are separated
from each other by additional structures.
Based on the QFN package and the special
JENCOLOR
®
interference filter technology, the
AS73210 is long-term stable over the entire
product
