IR Receiver Modules for Remote Control Systems
Description
The TSOP22..WE1 - 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
decoded by a microprocessor. TSOP22..WE1 is the
standard IR remote control receiver series, support-
ing all major transmission codes.
