DESCRIPTION
ORDERING CODE
The TSOP12... and TSOP14... series devices are the latest
generation miniaturized IR receiver modules for infrared
TSOP12..., TSOP14... - 2160 pieces in tubes
remote
control
systems.
These
series
provide
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.

AGC
The TSOP122.., TSOP124.., TSOP126.., TSOP142..,
TSOP144.., and TSOP146.. series devices are designed to
receive long burst codes (10 or more carrier cycles per
burst). The third digit designates the AGC level (AGC2,
AGC4, or AGC6) 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. AGC2 provides basic noise suppression,
AGC4 provides enhanced noise suppression and AGC6
provides maximized noise suppression. Generally, we
advise to select the highest AGC that satisfactorily receives
the desired remote code.
