Arduino Shield controls the current passing through LEDs

Analog Devices EVAL-CN0410-ARDZ Arduino Shield is optimised for smart agriculture to control the current passing through LEDs. The device is used along the CFTL-LED Bar that has LEDs with specific wavelengths that plants use. The circuit is a complete three-channel single-supply, 16-bit unbuffered voltage output DAC that sustains ±2LSB integral and differential nonlinearity by using a CMOS DAC. This circuit has a voltage-to-current conversion that regulates the amount of current passing through an LED by employing a MOSFET in its configuration. The circuit also includes an isoSPI repeater that enables multiple boards to be controlled by a single master. This board can be used with the EVAL-CN0410-ARDZ circuit board, the CFTL-LED-BAR, and the EVAL-ADICUP3029 wireless development platform.
