TSOP1838 IR Receiving Head

The TSOP1838 IR Receiver is a compact and highly reliable infrared receiving module designed for remote control and optical sensing applications. It integrates a PIN photodiode and preamplifier IC on a single lead frame, ensuring high sensitivity and stable performance.

The device is housed in a special epoxy package with an integrated IR filter, allowing it to operate efficiently even under strong ambient or fluorescent lighting conditions. With excellent immunity against electrical noise and light interference, the TSOP1838 delivers clean, demodulated digital output signals that can be directly decoded by microcontrollers such as Arduino, PIC, AVR, or ARM.

Operating at a standard 38kHz carrier frequency, the TSOP1838 is compatible with NEC, RC5, and other common IR remote control protocols, making it a universal solution for infrared communication. Supporting both 3.0V and 5.0V supply voltages, it is energy-efficient and ideal for battery-powered designs.
