IR Receiver Modules for Remote Control Systems
Description
The TSOP12..RF1 - 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. TSOP12..RF1 is the standard IR remote control receiver series, supporting all major transmission codes.
