IR Receiver Modules for Remote Control Systems

FEATURES

• Height of 0.8 mm

• ± 75° half angle sensitivity

• Low supply current

• Photo detectors and preamplifier in one

package

• Internal filter for PCM frequency

• Supply voltage: 2.5 V to 5.5 V, typically even

2.0 V to 5.5 V is possible

• Improved immunity against ambient light

• Insensitive to supply voltage ripple and noise

• Material categorization: For definitions of compliance

DESCRIPTION

The TSOP572.., TSOP574.. series are miniaturized receiver

modules for infrared remote control systems. A PIN diode

and a preamplifier are assembled on a lead frame, the epoxy

lens cap is designed as an IR filter.

The demodulated output signal can be directly decoded by

a microprocessor. The TSOP572.. is compatible with all

common IR remote control data formats. The TSOP574.. 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.
