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.

SUITABLE DATA FORMAT
This series is designed to suppress spurious output pulses
due to noise or disturbance signals. The devices can
distinguish data signals from noise due to differences in
frequency, burst length, and envelope duty cycle. The data
signal should be close to the device’s band-pass center
frequency (e.g. 38 kHz) and fulfill the conditions in the table
below.
When a data signal is applied to the product in the
presence of a disturbance, the sensitivity of the receiver is
automatically reduced by the AGC to insure that no spurious
pulses are present at the receiver’s output.
Some examples which are suppressed are:
• DC light (e.g. from tungsten bulbs sunlight)
• Continuous signals at any frequency
• Strongly or weakly modulated patterns from fluorescent
lamps with electronic ballasts (see Fig. 13 or Fig. 14)
• 2.4 GHz and 5 GHz Wi-Fi
