IR receiver/demodulator SFH505A
An increasing number of infra-red remote control circuits in video recorders and TV sets have an integrated infra-red receiver/demodulator. The advantages of such modules are clear: a smalI, less complex, circuit, and lower production costs. Furthermore, the combination of an IR receiver and a demodulator in one package increases the reliability of the remote control. This Siemens application note takes a further look at the SFH505A.
