ADT2688
General Description
The ADT2688 is a low current receiver IC for the high-end application infrared
remote control system. It has a wide voltage operating such as 2.7~5.5V, a very high
sensitivity.
These ICs are capable of accepting a photo diode directly and include many excellent
circuit such as 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.
