Description
The TSOP28..WE1 – series are miniaturized
receivers 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
decoded by a microprocessor. The main benefit is the
reliable function even in disturbed ambient and the
protection against uncontrolled output pulses.
