The 1838B is a miniaturised infrared receiver for remote control and other applications requiring improved ambient light rejection. The separate PIN diode and pre-amplifier IC are assembled on a single leadframe. The epoxy package contains a special IR filter. This module has excellent performance even in disturbed ambient light applications and provides protection against uncontrolled output pulses. The reciver can be powered from a 3.3V or 5V supply and with just one data output pin allows it to be easily interfaced with many types of microcontrollers.

Features:

• Photo detector and preamplifier in one package . 
• Internal filter for PCM frequency. 
• Inner shield,good anti-interference ability. 
• High immunity against ambient light. 
• Improved shielding against electric field disturbance 
• 3.0V or 5.0V supply voltage; low power consumption. 
• TTL and CMOS compatibility. 
• Suitable transmission code: NEC code,RC5 code.
