TSOP2438 IR Receiver Modules for Remote Control Systems

Miniaturized receiver for IR control systems. PIN diode and preamplifier are assembled on lead frame, the epoxy package is designed as IR filter. The demodulated output signal can directly be decoded by a microprocessor. The main benefit is the reliable function even in disturbed environment and the protection against uncontrolled output pulses.

Features

• Photo detector and preamplifier in one package
• Internal filter for PCM frequency
• TTL and CMOS compatibility
• Output active low
• Improved shielding against electrical field disturbance
• Suitable burst length ≥ 10 cycles/burst
• Low power consumption
• Advanced immunity against ambient light
• No occurrence of disturbance pulses at the output

Technical specifications
