ADT2690
General Description
The ADT2690 is a miniaturized receiver IC for infrared remote
control system.
It has a wide voltage operating such as 2.7~5.5V, a high sensitivity.
Wide operating voltage is very suitable to the hand-held battery
operating systems, e.g., electrical toy.
It has 4 trimming cells for the fined adjust of center frequency.
These ICs are capable of accepting a photodiode 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.
