DESCRIPTION
ORDERING CODE
These products are miniaturized receivers for infrared
remote control systems. A PIN diode and a preamplifier are
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.
TSOP3.... - 2160 pieces in tubes
BLOCK DIAGRAM
The TSOP323.., TSOP343..series devices are optimized to
suppress almost all spurious pulses from energy saving
lamps like CFLs. AGC3 may also suppress some data
signals if continuously transmitted.
VS
30 kΩ
OUT
The TSOP321.., TSOP341.. series are provided primarily for
compatibility with old AGC1 designs. New designs should
prefer the TSOP323.., TSOP343.. series containing the
newer AGC3. The TSOP325.., TSOP345.. series contain a
very robust AGC5. This series should only be used for
critically noisy environments.

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
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:
