The 1838B is miniaturized infrared receivers for remote control and other applications requiring improved ambient light rejection.
The separate PIN diode and preamplifier 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.
• 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.
1. Optical switch
