The LTOP-4136 IR remote receiver from Lite-On Technology Corporation is a compact 36kHz infrared receiver designed for applications requiring a decent range and simplicity. These devices typically show up in home automation setups, smart appliance control systems, and consumer electronics where an affordable yet reliable IR receiver is needed.

If you're working on a project that involves integrating remote control functionality without the need for complex protocols or long-range capabilities, the LTOP-4136 is a solid choice. One thing worth noting is its 35-meter range, which might be more than sufficient for most indoor applications but could be limiting in larger spaces. Engineers tend to reach for this when they need a straightforward solution for receiving IR signals from standard remote controls.

Another practical aspect is its 3-pin design, which simplifies wiring and integration into existing circuits. This makes it particularly appealing for DIY projects and smaller-scale electronics builds where minimizing component count and complexity is key. The 36kHz frequency is a common standard for many consumer remote controls, ensuring compatibility with a wide range of devices. Overall, the LTOP-4136 offers a balanced set of features that make it a reliable workhorse in the realm of IR signal reception.
