Vishay Semiconductors' Preamplifier Circuit for IR Remote Control is designed for use in an IR receiver application together with a photo pin diode. These Preamplifier Circuits for IR Remote Control are 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, Vishay Semiconductors' Preamplifier Circuit for IR Remote Control is immune to DC current caused by DC light sources such as tungsten bulbs. With these Preamplifier Circuits for IR Remote Control, the disturbance signal of fluorescent lamps is suppressed; there are no unwanted pulses at the output.
Features
Narrow bandpass filter 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
