XYZ Sensor

The AS7261N XYZ sensor is a next-generation digital color

sensor device. It senses X, Y, Z standard observer filters

compliant with the CIE 1931 standard observer color response

in addition to near IR (NIR), Clear (C) and Dark (D) spectrum

filters.

The sensor contains analog-to-digital converters (16-bit

resolution ADC), which integrate current from each channel’s

photodiode. Upon completion of conversion cycle, the

integrated result is transferred to the corresponding data

data is maintained.

Interference filters realize all filter responses and enable

minimal life-time drift and very high temperature stability.

Filter accuracy is affected by the optical angle of incidence

which itself is limited by an integrated aperture and an internal

micro-lens structure in the AS7261N. The package field of view

(PFOV) is ±20.5° to deliver the specified accuracy. External

optics can be used as needed to expand or reduce this built in

PFOV.
