ANALOG DEVICES EVAL-CN0503-ARDZ

EVAL-CN0503-ARDZ is a multichannel optical-based liquid measurement platform circuit evaluation board. The CN0503 is a reconfigurable multi-parameter optical liquid measurement platform capable of performing colorimetry, turbidity and fluorometry. The design minimizes complexity by using a highly integrated multimodal sensor front end capable of simultaneously driving four LEDs and synchronously measuring four pairs of photodiodes at a flexible sampling rate. Furthermore, the front end has on-chip digital filters and high ambient light rejection which allow the platform to operate regardless of environmental lighting conditions.
