The TSOP75338FTR is a miniaturized infrared (IR) receiver module from Vishay Semiconductors, designed for remote control systems. This device is specifically tuned to receive IR signals modulated at a carrier frequency of 38 kHz, a standard frequency used in many remote control applications.

Applications:

• Infrared Remote Control Systems
• Televisions (TVs)
• Set-Top Boxes (STBs)
• DVD Players
• Audio/Video (AV) Receivers

Features:

• Improved immunity against HF and RF noise
• Low supply current
• Photo detector and preamplifier in one package
• Internal filter for PCM frequency
• TTL and CMOS compatibility

Benefits:

• Simplified System Design: Integrates a photodiode, preamplifier, and signal processing circuitry into a single, compact package.
• High Noise Immunity: Provides robust performance in noisy environments, minimizing false triggers.
• Extended Operating Range: High sensitivity enables reliable reception from greater distances.
• Low Power Consumption: Helps to extend battery life in remote control applications.
• Easy Integration: Compact size allows for easy integration into various devices.

Additional Details:

The TSOP75338FTR operates at a supply voltage range of 2.5 V to 5.5 V and typically consumes very little power. It includes an automatic gain control (AGC) feature to compensate for variations in signal strength and distance. The output of the device is an active-low signal, meaning that it is normally high and goes low when a valid 38 kHz IR signal is detected.

This IR receiver is ideally suited for remote control applications in consumer electronics devices such as TVs, set-top boxes, DVD players, and audio/video receivers. Its high sensitivity, excellent noise immunity, and low power consumption make it an excellent choice for these applications.
