3 theory of operation the integral r,g,b color filters 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 components into photocurrents. the integrated transimpedence amplifiers for r,g,b components then converts the photocurrent 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
