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.
