IR Receiver for Remote Control Systems

The TSOP31238 device is a member of the TSOP312–TSOP314 Series IR receivers (D2),

which are miniaturized IR receivers designed to work with infrared remote control sys-

tems. A PIN diode and a preamplifier are assembled on a lead frame. The epoxy package

contains an IR filter. The demodulated output signal can be directly connected to a micro-

processor for decoding. See Figure 15 for an image of an IR receiver module.
