ams TMD37823 Color Sensor. Digital color sensor, proximity sensor and IR LED in an optical module with 1.8V I2C interface TMD37823

The TMD3782x device provides red, green, blue, and clear (RGBC) light sensing and proximity detection. The devices detect light intensity under a variety of lighting conditions and through a variety of attenuation materials, including dark glass. The proximity detection feature allows a large dynamic range of operation for accurate distance detection, such as in a cell phone, for detecting when the user positions the phone close to their ear. IR LED sink current is factory trimmed to provide consistent proximity response without requiring customer calibrations. An internal state machine provides the ability to put the device into a low power state in between proximity and RGBC measurements providing very low average power consumption. This data is transferred via an I2C to the host.
