Photo Modules for PCM Remote Control Systems
Available types for different carrier frequencies
DescriptionThe TSOP18..SB3V – series are miniaturized receiv-
ers for infrared remote control systems. PIN diode and
preamplifier are assembled on lead frame, the epoxy
package is designed as IR filter.
The demodulated output signal can directly be de-
coded by a microprocessor. The main benefit is the
reliable function even in disturbed ambient and the
protection against uncontrolled output pulses.
Features Photo detector and preamplifier in one package Internal filter for PCM frequency TTL and CMOS compatibility Output active low Improved shielding against electrical field distur-
bance Suitable burst length ≥6 cycles/burst
Special Features Small size package Supply voltage 3–6 Volt Enhanced immunity against all kinds of distur-
bance light No occurrence of disturbance pulses at the out-
put Short settling time after power on (<200s)
