OPT3002: OPT3002

I'm currently building a multispectral sensor by putting the opt3002 behind narrow bandpass filters. The Range of the opt3002 is great but the potential error of 10% is too high in my opinion. To minimise the error i would now like to put an array of opt3002s behind one bandpassfilter and average their readings. My Problem is, that this is not very elegant due to having a bunch of I2C slaves for every bandwidth. Is there any TI Product that bundels the opt3002's photodiode in an array together with ONE multichannel adc and an I2C Interface? Is there another Method to enhance the accuracy of the OPT3002? Is there a whole other Product to consider when building a multispectral sensor? Thanks in advance!
