TS4871IQT Application Field and Working Principle

TS4871IQT is a linear amplifier for audio applications. It is a stereo model with two channels: one for left audio and one for right audio. The design of the TS4871IQT is based on the classic Class-AB amplifier design. The entire circuit has a wide frequency range, allowing for the playback of audio signals from very low to very high frequencies.The TS4871IQT is designed to be highly efficient. The Class-AB design provides power efficiency and the combination of bipolar transistors allows the circuit to handle high-power audio signals. The amplifier can output up to 250 watts of power, which is ideal for applications such as sound reinforcement for live performances.The TS4871IQT also has an extremely low THD (Total Harmonic Distortion). This means that the audio played through the amplifier will be very close to the original source material. The low THD is achieved through the use of feedback circuits and low frequency filtering.The TS4871IQT has two input sections: one for Line level source, such as a CD player or a computer audio output, and one for microphone input level signals. It also has two output sections; one for a speaker system and one for headphones.The main power is supplied to the amplifier through a power supply. The TS4871IQT has an input noise floor of only -90 dBV, which is extremely low for an amplifier of this type. The power supply is designed so that the amplifier can operate from both AC and DC sources, allowing for more flexibility.Another feature of the TS4871IQT is that it can be directly connected to an external speaker system. This allows for more flexibility in design and greater control over the sound. The amplifier is designed for easy integration into an audio system, with the connectors labelled for quick connections.In terms of design, the TS4871IQT is a simple yet powerful amplifier. It is designed to be small enough to fit comfortably into a desktop enclosure, allowing it to be used in applications where space is limited. The small form factor also allows it to be used in applications such as portable PA systems.The TS4871IQT is a reliable and efficient amplifier for any application requiring high-quality audio. With its wide frequency range and low THD, it is perfect for applications such as home audio systems, sound reinforcement, and home theater systems. The amplifier is small, efficient, and capable of delivering high-quality sound, making it a great choice for audio applications.
