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.

Note

• Circuits for other carrier frequencies are available on request.

BLOCK DIAGRAM (simplified) APPLICATION CIRCUIT

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 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.

ASSEMBLY INSTRUCTIONS

Reflow Soldering

• Set the furnace temperatures for pre-heating and heating

in accordance with the reflow temperature profile as

shown in the diagram. Excercise extreme care to keep the

maximum temperature below 260 °C. The temperature

shown in the profile means the temperature at the device

surface. Since there is a temperature difference between

the component and the circuit board, it should be verified

that the temperature of the device is accurately being

measured

• Handling after reflow should be done only after the work

surface has been cooled off

Manual Soldering

• Use a soldering iron of 25 W or less. Adjust the

temperature of the soldering iron below 300 °C

• Finish soldering within 3 s

• Handle products only after the temperature has cooled

off.
