-The **EVAL-CN0397-ARDZ** board uses [[http://www.analog.com/ad8500|AD8500]], a low power, precision CMOS op amp with a low input bias current of a typical 1pA which is used in a transipedance amplifier configuration to convert the current output of the photodiodes into voltage. It also features [[http://www.analog.com/ad7798|AD7798]] a 3-channel, low noise, low power 16-bit ADC that converts the analog voltage into digital data in for the processing of data into light intensity. The circuit utilizes RGB photodiodes from Everlight with their peak sensitivities 620nm (**R**), 550nm (**G**) and 470nm (**B**).+The **EVAL-CN0397-ARDZ** board uses [[adi>ad8500|AD8500]], a low power, precision CMOS op amp with a low input bias current of a typical 1pA which is used in a transipedance amplifier configuration to convert the current output of the photodiodes into voltage.
