IR Receiver Modules for Remote Control Systems
DESCRIPTION
This IR receiver series is optimized for long burst remote
control systems in different environments. The customer
can chose between different IC settings (AGC variants), to
find the optimum solution for his application. The higher the
AGC, the better noise is suppressed, but the lower the code
compatibility.
The devices contain a PIN diode and a preamplifier
assembled on a lead frame. The epoxy package contains an
IR filter. The demodulated output signal can be directly
connected to a microprocessor for decoding. These
components have not been qualified to automotive
specifications.

FEATURES
• Individual IC settings to reach maximum
performance
• Immunity against noise (lamps, LCD TV, Wi-Fi)
LINKS TO ADDITIONAL RESOURCES • Low supply current
• Photo detector and preamplifier in one package
Product Page Marking Packages Holders Bends and Cuts • Supply voltage: 2.0 V to 5.5 V
• Material categorization:
for definitions of compliance please see
www.vishay.com/doc?99912

APPLICATIONS
• Infrared remote control systems

DESIGN SUPPORT TOOLS

• 3D models
• Window size calculator
