General Description
The ADT2688TN 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
