FEATURES

• Low supply current

• Photo detector and preamplifier in one package

• Internal filter for PCM frequency

• Improved shielding against EMI

• Supply voltage: 2.7 V to 5.5 V

• Improved immunity against ambient light

• Insensitive to supply voltage ripple and noise

• Component in accordance to RoHS 2002/95/EC and

WEEE 2002/96/EC

DESCRIPTION

The TSOP41.., TSOP43.. 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 directly be decoded by a

microprocessor. The main benefit of the TSOP41.. is the

compatibility to all IR remote control data formats. The

TSOP43.. is optimized to better suppress spurious pulses

from fluorescent lamps, LCD TVs or plasma displays.

This component has not been qualified according to

automotive specifications.
