ADT2450

5V Operating IR Receiver with Excellent Noise Performance for R/C ADT2450 General Description ADT2450 is a miniaturized receiver IC for use in the infrared remote control system. It has 5V voltage operating, a high sensitivity, and good noise immunity to a power and external light. This can also be suitable for high optical and electrical disturbances and good for an 5V application system. It has the frequency selecting Pads for setting the center frequency of band-pass filter and also has 5 trimming Pads for the fined adjust of center frequency. This IC is capable of accepting a photodiode directly and include many excellent circuit such as an internal voltage reference for better temperature characteristics, a high gain initial amplifier, a gain control amplifier, a limiter, a band pass filter, a detection circuit, two comparator circuits, gain control circuits, integrator circuits, a waveform shaping circuit assembled on a single chip. This IC also has a powerful noise suppression...
