AS7261/AS7262/AS7263 Color, Visible, and NIR Wavelength Sensors

ams OSRAM's AS7261, AS7262, and AS7263 are color, visible, and NIR wavelength sensors. The AS7261 is a white color chromatic sensor that can map XYZ coordinates consistent with CIE 1931 2° Standard Observer color coordinates. The sensor integrates Gaussian filters into standard CMOS technology and is packaged in a 20-pin LGA with a temperature range of -40°C to +85°C. The AS7261 come with a 16-bit analog-to-digital converter (ADC) programmable LED driver.

The AS7262 is a multi-spectral sensor-on-chip solution designed to address spectral ID applications. This device delivers 6-channel multi-spectral sensing in the visible wavelengths from approximately 430 nm to 670 nm with full-width half-max (FWHM) of 40 nm. An integrated LED driver with programmable current is provided for electronic shutter applications.

The AS7263 is a digital 6-channel spectrometer for spectral identification in the near IR (NIR) light wavelengths. AS7263 consists of six independent optical filters whose spectral response is defined in the NIR wavelengths from approximately 600 nm to 870 nm with full-width half-max (FWHM) of 20 nm. An integrated LED driver with programmable current is provided for electronic shutter applications. Control and spectral data access for all three sensors are implemented through either the I²C register set, or with a high-level AT spectral command set via a serial UART. They take a voltage supply from 2.7 V to 3.6 V. The AS7261, AS7262, and AS7263 are ideal for applications of color identification, matching, and control in the SMART world today.
