DESCRIPTION
The TSOP37... series are miniaturized SMD IR 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 TSOP374.. series devices are optimized to suppress
almost all spurious pulses from energy saving lamps like
CFLs. The AGC4 used in the TSOP374.. may suppress
some data signals. The TSOP372.. series are provided
primarily for compatibility with old AGC2 designs. New
designs should prefer the TSOP374.. series containing the
newer AGC4.
These components have not been qualified according to
automotive specifications.

SUITABLE DATA FORMAT
The TSOP372.., TSOP374.. 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 TSOP372.., TSOP374..
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)
