DESCRIPTION
The TSOP348.., TSOP344.. 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 TSOP348.. is compatible with all
common IR remote control data formats. The TSOP344.. 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.
