• Compliant to RoHS directive 2002/95/EC and in
DESCRIPTION
The TSOP48.., TSOP44.. 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 TSOP48.. is compatible with all
common IR remote control data formats. The TSOP44.. is
optimized to suppress almost all spurious pulses from
energy saving fluorescent lamps but will also suppress
some data signals.
This component has not been qualified according to
automotive specifications.
