1 / 11 page Document Number: 81904 www.vishay.com Rev. 1.2, 13-Aug-09 1 IR Receiver Module for Light Barrier Systems TSOP5038 Vishay Semiconductors MECHANICAL DATA Pinning: 1 = GND, 2 = N.C., 3 = OUT, 4 = VS FEATURES • Low supply current • Photo detector and preamplifier in one package • Internal filter for 38 kHz IR signals • Shielding against EMI • Supply voltage: 2.7 V to 5.5 V • Visible light is suppressed by IR filter • Insensitive to supply voltage ripple and noise • Compliant to RoHS directive 2002/95/EC and in accordance to WEEE 2002/96/EC DESCRIPTION The TSOP5038 is a compact SMD IR receiver for sensor applications. It has a high gain for IR signals at 38 kHz. The detection level does not change when ambient light or strong IR signals are applied. It can receive continuous 38 kHz signals or 38 kHz bursts.

The output voltage V O should not be pulled down to a level below 1 V by the external circuit. The capacitive load at the output should be less than 2 nF. |
