DESCRIPTION
The
PDI-E838
is a two drive line dual emitter
oximeter component. The 660 and 880 nm GaAlAs
infrared emitters are mounted in a glob toped low
cost ceramic SMT package. The LEDs are bias
separately by alternating polarity on the bias pins.
APPLICATIONS
鈥?Oximeter Probes
鈥?Finger Clamps
鈥?Reusable probes
