TSOP1338 / SM338E Infrared Receiver Module (38 kHz, DIP 3)

The TSOP1338 Infrared Receiver Module is designed to detect modulated infrared signals with a 38 kHz carrier frequency. It integrates a PIN photodiode, preamplifier, automatic gain control, and demodulation circuitry in a compact package. The module provides a digital output suitable for decoding infrared remote control signals using microcontrollers and embedded systems. The SM338E may be used as an alternative where its pinout and electrical characteristics are confirmed to be compatible.
