Functional Features

The TSOP39456 is designed to receive infrared signals modulated at a frequency of 56kHz. It filters out disturbances from sunlight and other light sources, ensuring reliable operation in various lighting conditions. The device demodulates the received IR signal and provides a digital output, making it suitable for use with microcontrollers and other digital logic circuits.

Advantages and Disadvantages

Advantages

• High sensitivity
• Low power consumption
• Reliable performance in varying light conditions

Disadvantages

• Limited to a specific carrier frequency
• Requires line of sight for signal reception

Working Principles

When an infrared signal at 56kHz is detected by the TSOP39456, it amplifies and demodulates the signal to produce a corresponding digital output. The device's internal circuitry filters out ambient light and noise, ensuring that only the modulated IR signal is processed.

Application Field Plans

The TSOP39456 is widely used in remote control systems for home appliances, audio-visual equipment, and air conditioning units. Its high sensitivity and reliable performance make it suitable for applications where precise and consistent signal reception is essential.

Alternative Models

For applications requiring different carrier frequencies or form factors, alternative models to the TSOP39456 include: - TSOP38256 (38kHz carrier frequency) - TSOP48456 (48kHz carrier frequency) - TSOP31256 (Through-Hole package, 56kHz carrier frequency)

In conclusion, the TSOP39456 is a highly sensitive and reliable infrared receiver suitable for a wide range of consumer electronics and remote control systems. Its compact design and low power consumption make it an ideal choice for manufacturers seeking dependable IR reception in their products.
