The OPB780Z is a full color sensor with 4

different frequencies relating directly to a

specific color seen by the sensor.

The OPB780Z color sensor uses a

p r o g r a m m a b l e

converter that combines 64 configurable

silicon photodiodes (on a 144 um center

array and measuring 120 um x 120 um

each)

converter on a single monolithic CMOS integrated

circuit, packaged in a small, lightweight package that

makes it ideal for using in miniature applications.

The output is a square wave (50% duty cycle) with a

frequency directly proportional to light chromaticity and

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

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.

group is also connected in parallel.

photodiode used during operation is pin-selectable.

The internal photodiode used by the device is controlled

by two logic inputs, S2 and S3.

The output of the device is designed to drive a standard

TTL or CMOS logic input over short distances.

The OPB780-Kit is designed to provide the design engineer an

easy way to evaluate the capability of the OPB780 Color Sensor.

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.
