IR Receiver Modules for Remote Control Systems

Description

The TSOP22..QJ1 - 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. TSOP22..QJ1 is the

standard IR remote control receiver series, support-

ing all major transmission codes.
