• Vout()d is the dark signal level of the analog sig-
nals. It is independent of illumination but propor-
tional to temperature.
• Vout()dc is the dc-level of the analog signals with
respect to the dark signal level. It is proportional
to illumination but independent of temperature.
• The permissible load current for the analog out-
puts is specified as parameter 211 in the Electrical
Characteristics.
• For correct functionality of the Z-index, program-
ming pin VZ has to be set to a proper value as de-
scribed in section INDEX DETECTION THRESH-
OLD.
