IR Receiver Modules for Remote Control Systems
Description
The TSOP48.. - 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. TSOP48.. is the standard IR remote control receiver series, supporting all
major transmission codes.
Features
• Photo detector and preamplifier in one package
• Internal filter for PCM frequency
TSOP48..
• Improved shielding against electrical field
disturbance
• TTL and CMOS compatibility
• Output active low
• Low power consumption
Special Features
• Improved immunity against ambient light
• Suitable burst length ≥ 10 cycles/burst
