DESCRIPTION

The TSOP382.., TSOP384.. series are miniaturized

receivers for infrared remote control systems. A PIN diode

and a preamplifier are assembled on a lead frame, the epoxy

package acts as an IR filter.

The demodulated output signal can be directly decoded by a

microprocessor. The TSOP382.. is compatible with all

common IR remote control data formats. The TSOP384.. is

optimized to suppress almost all spurious pulses from

energy saving fluorescent lamps but will also suppress some

data signals.

This component has not been qualified according to

automotive specifications.

SUITABLE DATA FORMAT

The TSOP382.., TSOP384.. series are designed to suppress

spurious output pulses due to noise or disturbance signals.

Data and disturbance signals can be distinguished by the

devices according to carrier frequency, burst length and

envelope duty cycle. The data signal should be close to the

band-pass center frequency (e.g. 38 kHz) and fulfill the

conditions in the table below.

When a data signal is applied to the TSOP382.., TSOP384..

in the presence of a disturbance signal, the sensitivity of the

receiver is reduced to insure that no spurious pulses are

present at the output. Some examples of disturbance signals

which are suppressed are:

• DC light (e.g. from tungsten bulb or sunlight)

• Continuous signals at any frequency

• Strongly or weakly modulated noise from fluorescent

lamps with electronic ballasts (see figure 15 or figure 16)
