OPB780-Kit
Color Sensor Evaluation Kit
? The OPB780-Kit is designed to provide the design engineer an
easy way to evaluate the capability of the OPB780 Color Sensor.
The OPB780Z is a full color sensor with 4
different frequencies relating directly to a
specific color seen by the sensor.
Block
The OPB780Z color sensor uses a

irradiance from four filtered diode arrays.
The light-to-frequency converter reads an 8 x 8 array of
photodiodes that consists of four groups of 16
photodiodes each, segregated by color: 16

photodiodes with red filters, 16 photodiodes with green
filters, 16 photodiodes with blue filters and 16
photodiodes with clear filters. Each color’s group of 16
photodiodes is interdigitated to minimize the effect of
non-uniformity of incident irradiance. Each color’s
group is also connected in parallel. The type of
photodiode used during operation is pin-selectable.
The internal photodiode used by the device is controlled
by two logic inputs, S2 and S3.

The OPB780Z includes 10” [25.4cm] a Flat Flexible
interface Cable. Custom lengths of the cable can be
ordered either from OPTEK or most Flat Flexible Cable
(FFC) manufactures. The FFC is designed to interface
with an any standard 0.5mm spacing FFC connector
similar to the AVX ELCO connector.
(part number 04 6249 0080 00 800+).
The output of the device is designed to drive a standard
TTL or CMOS logic input over short distances.
OPTEK reserves the right to make changes at any time in order to improve design and to supply the best product possible.
