IR Receiver Modules for Remote Control Systems
Description
The TSOP41.. - 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 short burst transmission codes and
high data rates.
Features
• Photo detector and preamplifier in one package
• Internal filter for PCM frequency
TSOP41..
• Improved shielding against electrical field disturbance
• TTL and CMOS compatibility
• Output active low
• Low power consumption
• High immunity against ambient light
Special Features
• Enhanced data rate of 4000 bit/s
• Operation with short bursts possible (≥ 6 cycles/
burst)
