n DESCRIPTION
The AIC1863 is a high performance infrared r emote control preamplifier.
Especially, it has e xcellent interference suppression capability.
The infrared pulses arriving at the photodiode are treated by the trans-impedance amplifier and amplified by the auto-gain control amplifier, limitter amplifier, and band-pass filter.
The following evaluation circuits, including the comparator, integrator, and schmitt-trigger, demodulate the transmitted digital signal.
Reduction of sensitivity due to external interference is achieved by the short-time boost and long-time control circuits, which prevent interference voltages fr...
