Overview
This IR demodulator from Vishay is a general-purpose receiver for IR-based remote-control projects. It is optimized for data rates up to 4000 bits/s and bursts as short as six cycles, and the detector’s epoxy package serves as an infrared filter that helps eliminate noise from visible light sources. The operating voltage range is broad enough for 5 V and 3.3 V logic, and unlike some receiver modules, the TSOP34156 allows for continuous reception. The module’s output signal can be directly connected to a microcontroller; no additional external components are required.
For a similar IR detector that is tuned for a 38 kHz carrier frequency, see the Vishay TSOP38438.
