Claiming to dramatically improve accuracy while cutting bill-of-materials (BoM) and production costs, the AS7261 JENCOLOR XYZ sensor is a complete platform for color sensing that eases design-in and simplifies production processes. Capabilities include a CCT and full-color sensor which provides direct XYZ color co-ordinates consistent with the CIE 1931 2° Standard Observer framework. It also maps the XYZ co-ordinates to the x, y (Y) of the two-dimensional color gamut and scales them to the CIE 1976 u’v’ coordinate system. Other features include a multi-channel filter set integrated at the silicon wafer level, calibrated CCT, x, y, u’v’ duv and direct sensor count outputs accessible via I2C or UART interfaces, a programmable LED driver, an aperture with integrated lensing built into the device’s 4.5 mm x 4.7 mm LGA package, and a simple text-based AT command set. The AS7261’s tri-stimulus XYZ color sensing capability enables it to mimic the human eye’s response curve, known as the ‘standard observer’ color model as represented by the CIE 1931 and CIE 1976 color mapping systems. The measurements of white light are typically accurate to ±0.002 du’v’ on the CIE 1976 scale. The AS7261 is available now in production volumes. Unit pricing is $4 each/1,000 units.
