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.
The TRS1722, TRS1755, and TRS1766 are high-sensitivity reflective color sensors designed to convert reflected light intensity into an output voltage. Each device integrates a colored LED light source, a photodiode light sensor with a matching optical color filter, a transimpedance amplifier, and on-board signal conditioning. The sensors operate on a single voltage supply and are available in a surface-mount package.
| Supply voltage | 3 to 5.5 V |
|---|---|
| Operating free-air temperature | -25°C to 85°C |
| LED forward current (max) | 10 mA |
| Wavelength (TRS1722) | 630 nm |
The sensors operate within a free-air temperature range of -25°C to 85°C.
The maximum supply voltage is 6V.
The typical output voltage with no load is 4.49 V.
