TSOP77538TR

Product Overview

TSOP77538TR is an infrared receiver module designed for remote control systems. It falls under the category of electronic components and is widely used in consumer electronics, such as televisions, DVD players, and set-top boxes. The module is characterized by its high sensitivity, low power consumption, and compact package. It is typically packaged in a small, surface-mount device (SMD) package and is available in various quantities to suit different production needs.

Specifications

• Operating Voltage: 2.5V to 5.5V
• Carrier Frequency: 38kHz
• Supply Current: 350µA
• Transmission Range: Up to 45m
• Package Type: SMD

Detailed Pin Configuration

The TSOP77538TR module typically consists of three pins: 1. OUT - Output pin for the demodulated signal 2. GND - Ground connection 3. VS - Power supply input

Functional Features

The module is designed to receive infrared signals modulated at a frequency of 38kHz. It can demodulate these signals and provide a clean output for further processing. The TSOP77538TR has a built-in automatic gain control (AGC) to ensure reliable operation even in varying ambient light conditions.

Advantages and Disadvantages

Advantages

• High sensitivity
• Low power consumption
• Wide operating voltage range
• Long transmission range

Disadvantages

• Limited carrier frequency compatibility
• Susceptible to interference from other light sources

Working Principles

When exposed to infrared signals modulated at 38kHz, the TSOP77538TR demodulates the incoming signal and provides a corresponding output. The AGC feature helps maintain a consistent output level, regardless of ambient light variations.

Detailed Application Field Plans

The TSOP77538TR is commonly used in remote control systems for various consumer electronics, including TVs, audio systems, and air conditioners. Its high sensitivity and long transmission range make it suitable for applications where reliable remote control operation is essential.
