Description
The TSOP52.. – series are miniaturized SMD–IR
Receiver Modules 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. TSOP52.. is the
standard IR remote control SMD–Receiver series,
supporting all major transmission codes.
