DESCRIPTION
The VSOP584.. is designed for use in an IR receiver
application together with a photo pin diode. It is a
sophisticated receiver concept that is very sensitive to data
signals and compatible with the most common data formats
for IR remote control. On the other hand it is immune to DC
current caused by DC light sources such as tungsten bulbs.
The disturbance signal of fluorescent lamps is suppressed;
there are no unwanted pulses at the output.

Vishay recommends using a photodiode with at least
2.3 mm2 area. The connection between the photodiode and
pin 7 should be kept as short as possible and carefully
shielded to prevent noise coupling.

The RC filter is optional to improve the EOS robustness
and the immunity to supply voltage ripple. We recommend
to keep the distance between the photodiode and the input
of the VSOP584.. as short as possible.
