DESCRIPTION
MECHANICAL DATA
Pinning:
1 = GND, 2 = V
S
, 3 = OUT
The TSOP12.. 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 TSOP12.. is compatible with all
common IR remote control data formats.
This component has not been qualified according to
automotive specifications.

IR Receiver Modules for Remote

SUITABLE DATA FORMAT
The TSOP12.. series is 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 TSOP12.. 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)
