DESCRIPTION

The TSSP77P38 is a compact infrared detector module for

proximity sensing application. 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

• Very low supply current

• Photo detector and preamplifier in one package

• Shielding against EMI

• Supply voltage: 2.0 V to 5.5 V

• Visible light is suppressed by IR filter

• Capable of side or top view

• Insensitive to supply voltage ripple and noise

• Two lenses for high sensitivity and wide

receiving angle

• Material categorization: for definitions of compliance
