Digital RGB + IR / Ambient Light, OB1203 Proximity, Pulse Oximeter and Preliminary Heart-Rate Sensor Short-Form Datasheet Description Color Sensor Features
IDT’s OB1203 Sensor Module integrates a multi-channel light  Four parallel channels (red, green, blue, clear) sensor (LS/CS), a proximity sensor (PS), and a photoplethys-  Accurate correlated color temperature (CCT) mography sensor (PPG).  Accurate CIE 1931 XYZ (RGB) color measurement The light sensor can be configured as an ambient light sensor (LS)  Very stable spectral response over angle of light incidence to measure ambient light similar to the human eye experience or as an RGB color sensor (CS). The module has a fully integrated  Output resolution for CS: 13 to 20 bits biosensor for reflective photoplethysmography. With the approp- riate algorithm, it can determine the human heart rate, oxygen

The OB1203 integrates light sources and  Integrated and trimmed LED source, driver, and photodetector drivers in a single optically optimized package.  Programmable, pulsed LED up to 250mA output current A major LS application for the device is in smart phones or other  High resolution (12 to 16 bits) mobile devices to enable brightness control of display panels. The  Object movement detection (in/out) OB1203 can also determine proximity of nearby objects in order to  Ambient light suppression > 100 klx sunlight support the activation of touch screen displays or system functions.  Crosstalk cancelation (analog and digital) The sensor combines optical sensing features (CS, LS, PS) and bio-sensing functionality (PPG) without needing a visible optical opening. The unique implementation of the OB1203 enables SpO
