DESCRIPTION
The VSOP383.. 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.
FEATURES • Narrow bandpassfilter for all common carrier
frequencies • High immunity against DC light • Intelligent AGC to suppress disturbance from
fluorescent lamps and CRTs • Low power consumption • Wide supply voltage range • High immunity against ripple on the supply voltage • Output active low • IC manufactured in CMOS technology • Small QFN package with 2 mm width • Material categorization: for definitions of compliance

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 VSOP383.. as short as possible.
