Manufacturer: Description: In operation, ambient light can occasionally cause an infrared receivers bias level to drift towards VSS, possibly tripping the 1N4002s schmitt trigger input. As the receiver output drifts high again, the Schmitt trigger may not always reset, so that it might appear that there is carrier present when it is not. This condition is accounted for within the integrated circuit by momentarily changing pin 5 to a high level output before taking any measurements, thus reseting the trigger. The series resistor must be used on pin 5 to protect both circuits during this momentary high level pulse. Typically a value of 4.7KΩ is sufficient. |
