IR Receiver Modules for Remote Control Systems
Description
The TSOP41..UH1 - 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
Improved shielding against electrical field distur-
bance
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)
