Description

The TSOP28.. – series are miniaturized receivers for

infrared remote control systems. PIN diode and pre-

amplifier 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.
