IR Receiver Modules for Remote Control Systems
New TSOP348.., TSOP344..
Vishay Semiconductors
MECHANICAL DATA
Pinning:
1 = OUT, 2 = GND, 3 = VS
FEATURES
• 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 RoHS 2002/95/EC and
WEEE 2002/96/EC
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.
