IR Receiver Modules for Remote Control Systems
1 = OUT,
2 = GND,
3 = V S
•Very low supply current
•Photo detector and preamplifier in one package •Internal filter for PCM frequency •Improved shielding against EMI
•Supply voltage: 2.5 V to 5.5 V
•Improved immunity against ambient light •Insensitive to supply voltage ripple and noise
•Component in accordance to RoH S 2002/95/EC and WEEE 2002/96/EC
The TSOP341.., TSOP343.. series are miniaturized receivers for infrared remote control systems. A PIN diode and a preamplifier are assembled on a lead frame, the epoxy package acts as an IR filter.
The demodulated output signal can be directly decoded by a microprocessor. The TSOP341.. is compatible with all common IR remote control data formats. The TSOP343.. is optimized to better suppress spurious pulses from energy saving fluorescent lamps but will also suppress some data signals.
This component has not been qualified according to automotive specifications.
