IR Receiver Modules for Remote Control Systems

Description

The TSOP69.. - 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. The main benefit is the

operation with a high envelope duty cycle datasignal

and the good immunity against disturbance signals

with spike characteristic as well as all continuous dis-

turbance signals.
