The RPM840-H11E2 is an infrared receiver module manufactured by Rohm Semiconductor. These modules are designed to receive infrared signals transmitted by remote controls and other infrared devices, demodulate the signals, and output them as electrical signals. They are commonly used in a wide range of consumer electronics and industrial applications where remote control functionality is required.

Applications

• Television sets and set-top boxes
• DVD and Blu-ray players
• Audio equipment (receivers, amplifiers, soundbars)
• Air conditioners and other home appliances
• Remote-controlled toys and robots
• Industrial control systems

Features

• Miniature package for space-saving designs
• High sensitivity and long reception range
• Excellent noise immunity against ambient light and electrical interference
• Built-in preamplifier and automatic gain control (AGC)
• 3.0V to 5.5V operating voltage
• Carrier frequency of 38kHz

Benefits

• Enables reliable remote control functionality in electronic devices
• Reduces the size and cost of remote control receivers
• Simplifies circuit design with integrated components
• Provides stable performance in various operating environments
• Low power consumption contributes to energy efficiency

Additional Details

The RPM840-H11E2 integrates a photodiode, preamplifier, and demodulation circuit into a single molded package. The AGC circuitry automatically adjusts the receiver's sensitivity to maintain a stable output signal even with variations in the received infrared signal strength. The module is designed to be highly resistant to noise from fluorescent lights, incandescent lights, and other sources of interference. The output signal is typically a logic-low signal when an infrared signal is received and a logic-high signal when no signal is present. It has a center frequency of 38 kHz. The supply current is typically around 0.7mA. It is RoHS compliant.
