IR Receiver Modules for Remote Control Systems

Description

The TSOP348.. - 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. TSOP348.. is the stan-

dard IR remote control receiver series for 3 V supply

voltage, supporting all major transmission codes.
