Vishay Intertechnology, Inc. Optical Sensors - Optical Sensors - Photo Detectors - Remote Receiver - TSOP2238 TSOP2238

The TSOP2238 is an infrared receiver module designed for remote control applications, optimized for long burst codes. It operates at a carrier frequency of 38 kHz and supports a supply voltage range of 2.0 V to 5.5 V, with a low supply current of approximately 0.35 mA at 3.3 V. The device features a built-in PIN diode and preamplifier, allowing for direct connection to microprocessors for signal decoding. It offers immunity against noise from various sources, such as lamps and Wi-Fi, making it suitable for diverse environments. The operational temperature range is from -25 ¬8C to 85 ¬8C, and it has a maximum transmission distance of 24 meters under optimal conditions. The TSOP2238 is packaged in a through-hole format and is not qualified for automotive applications.
