Description
The TRS1722, TRS1755, and TRS1766 are high-sensitivity reflective color sensors in red (630 nm), green
(567 nm), and blue (470 nm) — respectively — with light-to-voltage converters. Each device consists of a
colored LED light source, a photodiode light sensor with matching optical color filter, a transimpedance amplifier,
and on-board signal conditioning. Output voltage is directly proportional to the reflected light intensity on the
photodiode plus any ambient light (which may be considered noise).

† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: All voltages are with respect to GND.
