DESCRIPTION
The TSOP4038 is a compact 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 external components R1 and C1 are optional to improve the robustness against electrical overstress (typical values are R1 = 100 Ω, C1 = 0.1 µF). The output voltage VO 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.

Note • Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect the device reliability. Rev. 1.2, 28-Mar-12 1 Document Number: 81926
