DESCRIPTION
BLOCK DIAGRAM
The TSOP94... series devices are the latest generation
miniaturized IR receiver modules for infrared 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.
VS
30 kΩ
OUT
Input
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.

PIN
The TSOP943.. and TSOP945.., 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.

SUITABLE DATA FORMAT
Axis Title
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.
10000
7
6
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:
