DESCRIPTION
The TSOP312.., TSOP314..series are miniaturized IR
receiver modules for infrared remote control systems. A PIN
diode and a preamplifier are assembled on a leadframe, the
epoxy package contains an IR filter.
The demodulated output signal can be directly connected to
a microprocessor for decoding.
The TSOP314.. series devices are optimized to suppress
almost all spurious pulses from energy saving lamps like
CFLs. The AGC4 used in the TSOP314.. may suppress
some data signals. The TSOP312.. series are provided
primarily for compatibility with old AGC2 designs. New
designs should prefer the TSOP314.. series containing the
newer AGC4.
These components have not been qualified according to
automotive specifications.

SUITABLE DATA FORMAT
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.
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:
• 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. 14 or Fig. 15).
