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

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.
BLOCK DIAGRAM (simplified)
Vishay recommends using a photodiode with at least
2.3 mm
2
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 lter 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.

• Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only
and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification
is not implied. Exposure to absolute maximum rating conditions for extended periods may affect the device reliability.
