| The circuit shown below 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 transimpedance 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. Gain resistor for each of the channel had been calculated to maximize the full scale of the ADC and additional filtering to remove unwanted signals. | The circuit shown below 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 transimpedance amplifier configuration to convert the current output of the photodiodes into voltage.
