Description

The TSOP18..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 de-

coded by a microprocessor. The main benefit is the

reliable function even in disturbed ambient and the

protection against uncontrolled output pulses.
