TSOP14556 Infrared Receiver Module

Product Overview

The TSOP14556 is an infrared receiver module designed for remote control applications. It falls under the category of electronic components and is commonly used in consumer electronics for receiving and decoding infrared signals from remote controls. The module's characteristics include high sensitivity, low power consumption, and compatibility with various carrier frequencies. It is typically packaged in a compact, surface-mount device (SMD) package and is available in tape and reel packaging with a specified quantity per reel.

Specifications

• Supply Voltage: 2.5V to 5.5V
• Carrier Frequency: 56kHz
• Supply Current: 350µA
• Operating Temperature: -25°C to 85°C
• Output Voltage: 0.4V (min) / Vcc (max)

Pin Configuration

The TSOP14556 module features a standard pin configuration with three pins: 1. OUT (Output) 2. GND (Ground) 3. VS (Supply Voltage)

Functional Features

The module is designed to receive modulated infrared signals at a frequency of 56kHz and convert them into corresponding electrical signals. It incorporates a photo detector, preamplifier, internal filter, and demodulator to ensure reliable signal reception and decoding.

Advantages and Disadvantages

Advantages

• High sensitivity to infrared signals
• Low power consumption
• Wide supply voltage range
• Compact SMD package

Disadvantages

• Limited to specific carrier frequency (56kHz)
• Susceptible to interference from ambient light sources

Working Principles

When exposed to modulated infrared light at 56kHz, the TSOP14556's photo detector generates a corresponding electrical signal. This signal is then amplified and filtered to remove noise and interference, after which the demodulator extracts the original modulating signal for further processing.

Application Field Plans

The TSOP14556 is widely used in various remote control applications, including but not limited to: - Television sets - Set-top boxes - Air conditioners - DVD/Blu-ray players - Home theater systems

Alternative Models

For those seeking alternative infrared receiver modules, the following options are available: - TSOP38256: Similar specifications with a different carrier frequency (38kHz) - TSOP48456: Higher sensitivity variant with a wider supply voltage range

In conclusion, the TSOP14556 infrared receiver module offers a reliable and efficient solution for remote control applications in consumer electronics, despite its limitations related to carrier frequency and ambient light interference.
