The RPM883-H12E4A is an infrared remote control receiver module manufactured by Rohm Semiconductor. It's designed to receive infrared signals transmitted by remote controls, demodulate the signals, and output a digital signal. This signal can then be used by a microcontroller or other circuitry to control the device. It is primarily used in consumer electronics for remote control applications.

Applications

• Televisions and set-top boxes
• DVD and Blu-ray players
• Audio equipment (receivers, amplifiers, soundbars)
• Air conditioners and other home appliances
• Lighting control systems
• Industrial control systems

Features

• Compact package size
• High sensitivity and long reception range
• Excellent immunity to ambient light and electrical noise
• Built-in preamplifier and AGC (Automatic Gain Control) circuit
• Carrier Frequency: 36.7 kHz
• Supply Voltage: 4.5V to 5.5V

Benefits

• Provides reliable infrared remote control reception
• Simplifies circuit design
• Reduces board space requirements
• Ensures stable performance in various operating environments

Additional Details

The RPM883-H12E4A integrates a PIN photodiode, a preamplifier, and a demodulation circuit in a single package. The AGC circuit automatically adjusts the receiver's sensitivity to maintain a stable output signal even with variations in the received infrared signal strength. It has a center frequency of 36.7kHz and is designed to suppress noise from fluorescent lights, incandescent lights, and other sources of interference. The output signal is active low. The peak sensitivity wavelength is 940nm. The typical supply current is 0.7mA. It is RoHS compliant.
