Notes:
1. At 1.0 m A 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 eri st ics ar e r equired at low input
currents.
2. Out put resistanc e vs input current tr ansfer curves are gi ven for
the foll owing li ght adapt conditions:
(1) 25 °C — 24 hour s @ no input
(2) 25 °C — 24 hour s @ 40 mA input
(3) +5 0°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.
