DESCRIPTION
n
The AIC1863 is a high performance infrared remote control preamplifier. Especially, it has excellent 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 from affecting
the output.
