DESCRIPTION
The TSOP98... 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 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 TSOP983.. and TSOP985.. series devices are designed
to receive short burst codes (6 or more carrier cycles per
burst). The third digit designates the AGC level (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.
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.
