Notes:
1. At 1. 0 mA and below, units may hav e substanti ally higher
resi stance than sho wn in the typica l curv es. Consul t factory i f
closely controll ed charact eristics are requi r ed at l ow input
currents.
2. Out put resistance vs input curr ent t r ansfer curves are gi ven for
the following light adapt condition s:
(1) 25 °C — 24 hour s @ no in put
(2) 25 °C — 24 hour s @ 40 mA in put
(3) +50°C — 24 hour s @ 40 mA input
(4) –2 0°C — 24 hour s @ 40 mA input
3. Response time characteristi cs ar e based upon test following
adapt condition (2) above.
