The AS73211 is a low power, low noise integrated color sensor. Three channels convert light signals into digital results via photodiodes, enabling continuous or triggered measurements. Three photodiodes are mounted in front of optical filters for the x, y and z signals. Ray responsivity can be set to 12 levels, with each step being 2 times. The conversion time is controlled internally and ranges from 15 steps to a factor of 2 each. The conversion time can be controlled externally via the input pin (syn), adapting the measurement to a given environment and time base.

INTRODUCTION
This document describes the hardware of the AS73211-AB5 designed by ams Sensors Germany. The OEM
sensor solution is a small PCB for general color measurement and control applications, with a high
bandwidth for light energy and optimized for handheld applications. The board is suitable for benchmarks,
feasibilities or as OEM solutions for tests.
The sensor board includes the True Color sensor AS73211 with I²C interface [1], which filters are based on
the international CIE 1931 standard. The sensor also includes an analog-to-digital converter which realizes
a current-to-capacity digitizing within a high dynamic range and 20 Bit ADC solution. Further components
on board are an EEPROM, power regulator and a standard I²C-interface. I²C is used for external
communication, configuration of the sensor, readout of the sensor data as well as reading and writing of
the memory. Figure 1 shows the block diagram.
At the I²C Bus is also still the EEPROM connected. The bus is directly accessible via a connector. The power
supply of the module is also carried out via this connector. A linear regulator generates the system voltage
and supplies via filter the analog and digital circuit of the sensor.
