DESCRIPTION
The TSSP57P38 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.

  • Page 5 Vishay Semiconductors The typical application of the TSSP57P38 is a reflective sensor with analog information contained in its output. Such a sensor is evaluating the time required by the AGC to suppress a quasi continuous signal. The time required to suppress such a signal is longer when the signal is strong than when the signal is weak, resulting in a pulse length corresponding to the distance of an object from the sensor.
