DESCRIPTION
ORDERING CODE
Taping:
TSOP37...TT1 - top view taped
TSOP37...TT2 - top view taped
The TSOP373.., TSOP375.. series are miniaturized receiver
modules for infrared remote control systems. A PIN diode
and a preamplifier are assembled on a PCB, the epoxy
package contains an IR filter. The demodulated output
signal can be directly connected to a microprocessor for
decoding.
The TSOP373.. 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.
New designs should prefer the TSOP373.. series containing
the newer AGC3. The TSOP375.. series contain a very
robust AGC5. This series should only be used for critically
noisy environments.
These components have not been qualified according to
automotive specifications.

SUITABLE DATA FORMAT
The TSOP373.., TSOP375.. 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 TSOP373.., TSOP375..
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)
