DESCRIPTION
The TSOP18... series devices are the latest generation
miniaturized IR receiver modules for infrared remote control
systems. This series provides improvements in sensitivity to
remote control signals in dark ambient as well as in
sensitivity in the presence of optical disturbances e.g. from
CFLs. The robustness against spurious pulses originating
from Wi-Fi signals has been enhanced.
The devices contain a PIN diode and a preamplifier
assembled on a lead frame. The epoxy package contains an
IR filter. The demodulated output signal can be directly
connected to a microprocessor for decoding.
The TSOP181.., TSOP183.., and TSOP185.. series devices
are designed to receive short burst codes (6 or more carrier
cycles per burst). The third digit designates the AGC level
(AGC1, AGC3, or AGC5) and the last two digits designate
the band-pass frequency (see table below). The higher the
AGC, the better noise is suppressed, but the lower the code
compatibility. AGC1 provides basic noise suppression,
AGC3 provides enhanced noise suppression and AGC5
provides maximized noise suppression. Generally, we
advise to select the highest AGC that satisfactorily receives
the desired remote code.
These components have not been qualified to automotive
specifications.
