Optical sensors are used in a variety of ways to detect the absorption of light in experiments or industrial processes. By using photo-conductive materials such as Tungsten Silicate Layer-6 Titanium Oxide (TSOP6256TR), precise detection measurements can be obtained. It works as an infrared receiver for remote control applications such as TVs, CD players, etc. In this article, the application field and working principle of the TSOP6256TR will be discussed.

TSOP6256TR Application Field

The TSOP6256TR is used as an infrared receiver for digital remote control applications. It is mostly used in TV and audio/visual remote controls, as well as wireless keyboards or mice. This device is a PIN photodiode with an integrated preamplifier, hence it is used to improve the sensitivity of the infrared detectors. It is the most commonly used infrared receiver due to its reliability, efficiency and cost.

The TSOP6256TR features a wide supply voltage range (2.4V to 5.5V) making it well suited for consumer electronics. It has an extremely fast response time of 9.5μs making it ideal for high-speed data transmission. It also has a wide optical power input range of 0.5mW/cm2 to 50mW/cm2, with an excellent modulation depth of 70%.

Working Principle

The TSOP6256TR is a PIN photodiode with an integrated preamplifier. When the infrared remote control is activated, it will emit pulses of modulated infrared light at 38kHz frequency. The TSOP6256TR is designed to receive and amplify these signals. The PIN diode in the device converts the modulated IR signal into an electrical signal. The integrated preamplifier further amplifies the signal before it is sent to the rest of the circuit.

The TSOP6256TR also features an optical filter that is designed to filter out any unnecessary noise from the signal. This ensures that only the signal corresponding to the transmitter frequency is accepted. The device is designed to be very sensitive, hence only a small amount of energy is necessary to trigger the device. The output of the device can be read as a logic low or logic high depending on the level of the input signal received.

In addition, the TSOP6256TR has a wide operating temperature range from -40°C to 85°C, which makes it well suited for a variety of environments. It also has a low power consumption of 1.5mA (max), and a low standby current of 0.6μA (typ). This makes it an efficient and economical solution for remote control applications.

The TSOP6256TR is a versatile and reliable infrared receiver that is commonly used in digital remote control applications due to its ease of use, reliability, and low power consumption. It is an excellent choice for detecting modulated infrared signals, and its wide supply voltage range and wide operating temperature range make it a practical solution for a variety of applications.
