# TSOP38136 Product Series Introduction
## 1. Overview
The TSOP38136 product series is a highly advanced and reliable line of infrared receivers designed for a wide range of applications. These receivers are engineered to provide exceptional performance in detecting and decoding infrared signals, making them an ideal choice for various consumer electronics, industrial, and automotive systems.
## 2. Key Features
### 2.1 High Sensitivity
The TSOP38136 series offers extremely high sensitivity to infrared signals. This allows it to detect even weak infrared transmissions from a considerable distance. Whether it's a remote - control signal sent from across a large room or an infrared communication signal in an industrial environment, the receiver can pick up the signal accurately, ensuring reliable operation.
### 2.2 Wide Operating Range
These receivers have a wide operating voltage range, typically from 2.7V to 5.5V. This flexibility makes them suitable for use in different power supply scenarios, whether it's a battery - powered device or a device connected to a standard power source. Additionally, they can operate effectively over a wide temperature range, from - 25°C to +85°C, which is crucial for applications in various environmental conditions.
### 2.3 Excellent Immunity to Interference
The TSOP38136 series is equipped with advanced filtering and signal - processing techniques to provide excellent immunity to ambient light and electrical interference. It can effectively reject unwanted signals caused by sunlight, fluorescent lights, or other electromagnetic sources. This ensures that the receiver only responds to the intended infrared signals, reducing false triggering and improving the overall reliability of the system.
### 2.4 Fast Response Time
With a fast response time, the TSOP38136 can quickly detect and decode incoming infrared signals. This is particularly important in applications where real - time communication is required, such as in remote - controlled toys, home automation systems, and automotive infrared sensors. The fast response enables seamless and immediate operation of the controlled devices.
### 2.5 Small Form Factor
The receivers in the TSOP38136 series are designed with a small form factor. This makes them easy to integrate into compact electronic devices without taking up much space. Their small size also allows for more flexible placement within the device, enabling designers to optimize the overall layout and functionality of the product.
## 3. Technical Specifications
### 3.1 Signal Frequency
The TSOP38136 is designed to operate at a specific carrier frequency of 36kHz. This frequency is commonly used in infrared remote - control systems, ensuring compatibility with a wide range of existing infrared transmitters.
### 3.2 Output Signal
The output of the TSOP38136 is an active - low signal. When an infrared signal is detected and decoded, the output pin goes low, indicating the presence of a valid signal. This simple digital output makes it easy to interface with microcontrollers and other digital circuits.
### 3.3 Supply Current
The supply current of the TSOP38136 is relatively low, typically in the range of a few milliamperes. This low power consumption is beneficial for battery - powered devices, as it helps to extend the battery life and reduce the overall power requirements of the system.
### 3.4 Detection Angle
The receiver has a wide detection angle, usually around ±45°. This wide angle allows it to receive infrared signals from different directions, providing greater flexibility in the placement of the transmitter and the receiver. It is especially useful in applications where the infrared signal may not be transmitted directly towards the receiver.
