2 theory of operation the integral r,g,b color flters on the photodiode array detect the r,g,b components of the light falling on the sensor. the photodiode convert the r,g,b light compo - nents into photocurrents. the integrated transimpedence amplifers for r,g,b components then converts the pho - tocurrent to analog voltage outputs. the voltage output of each r,g,b channel increases linearly with increasing light intensity. sensor ic block diagram pin out for ADJD-E622-QR999 pin pin name normal operation pin 1 vb out analog output voltage for blue pin 2 vg out analog output voltage for green pin 3 vr out analog output voltage for red pin 4 vdd 5v dc supply pin 5 gsgrn2 gain selection green bit 2 pin 6 gsgrn1 gain selection green bit 1 pin 7 gsred2 gain selection red bit 2 pin 8 gsred1 gain selection red bit 1 pin 9 gsred0 gain selection red bit 0 pin 10 nc no connection pin 11 nc no connection pin 12 gsblue0 gain selection blue bit 0 pin 13 gsblue1 gain selection blue bit 1 pin 14 gsblue 2 gain selection blue bit 2 pin 15 gsgrn 0 gain selection green bit 0 pin 16 gnd ground
