7. OPERATIONAL AND FUNCTIONAL DESCRIPTION
The appropriate RPD is determined by the characteristic of the luminance sensor being used and this IC's
VPD for brightness evaluation.
The following table shows IPDs for brightness evaluation with sense resistor RPD=100kΩ.
VPD1=0.003
VPD2=0.004
VPD3=0.006
VPD4=0.010
VPD5=0.016
VPD6=0.026
VPD7=0.040
VPD8=0.063
VPD9=0.079
VPD10=0.126
VPD11=0.173
VPD12=0.299
VPD13=0.472
VPD14=0.787
