DESCRIPTION

The TSSP4P38 is a compact infrared detector module

for proximity sensing applications. It receives 38 kHz

modulated signals and has a peak sensitivity of 940 nm.

The length of the detector’s output pulse varies in proportion

to the amount of light reflected from the object being

detected.

FEATURES

• Up to 2 m for proximity sensing

• Uses modulated bursts at 38 kHz

• Photo detector and preamplifier in one package

• Low supply current

• Shielding against EMI

• Visible light is suppressed by IR filter

• Insensitive to supply voltage ripple and noise

• Supply voltage: 2.0 V to 5.5 V

• Material categorization: for definitions of
