The TS4871IDT is a stereo audio amplifier integrated circuit from Texas Instruments (TI). These stereo audio amplifiers are used in a wide variety of consumer applications including soundbars and speakers for televisions, portable audio systems, car audio systems and PCs. The TS4871IDT is a Class-AB amplifier with an output power rating of up to 18 watts per channel, making it ideal for small to mid-sized systems. The amplifier is designed to operate from a dual voltage supply (6V/supply) and provides an excellent combination of power and efficiency thanks to its Bipolar Junction Transistors (BJT) output stage.

The TS4871IDT offers an active-load high-performance topology which differs from traditional load-based designs, resulting in minimised noise and distortion. This high-performance factor is further enhanced by the robust differential inputs which are capable of handling signals with a wide dynamic range and eliminating cross-talk between the left and right channels. The TS4871IDT also features thermal protection circuitry, which ensures that the amplifier is not damaged by excessive current or temperature. This additional protection also helps to maintain consistent output performance over a wide range of environmental conditions.

At the heart of the TS4871IDT is its Class-AB output stage, which operates in a push-pull configuration. The output stage is composed of various complementary Bipolar Junction Transistors (BJTs) which are arranged in a bridge-tied load (BTL) configuration. In this configuration, the output transistors are connected so that their outputs are opposed to one another, and the resulting current flows in opposite directions. This allows for power to be amplified efficiently, resulting in high levels of output power. Additionally, the BTL configuration helps to reduce distortion, as the output waveforms from each output transistor are identical, resulting in fewer odd harmonic distortions.

The TS4871IDT is specifically designed to operate from a dual voltage supply, allowing for operation on a wide range of input voltages. The device will operate within a range of 3V to 18V, allowing for operation in various environments. In addition, the device has a wide range of protected voltage levels, ensuring that the device is not damaged by unexpected voltage spikes or shorts. For example, the device has an Absolute Maximum Input Voltage of 24V, and an Absolute Maximum Output Voltage of ±36V. These high voltage ratings help to ensure reliable operation of the device in various environments.

The TS4871IDT is designed to provide excellent audio performance while being energy efficient. The device is capable of delivering up to 18 watts per channel, while still maintaining an efficiency rating of up to 78%. This allows for the device to be used in a wide range of applications, from home audio systems to automotive sound systems, with minimal power draw. Additionally, the TS4871IDT is designed to have an extremely low Total Harmonic Distortion (THD) rating of 0.02%. This low distortion rating ensures that the audio signal is accurately reproduced, providing listeners with a crisp and clear sound.

The TS4871IDT is an ideal solution for any applications requiring an efficient and high-performance stereo audio amplifier. This device offers a combination of power, efficiency, protection and excellent audio performance, making it a great choice for a variety of applications. The device offers a wide range of protected voltages, low THD, and efficient output power, making it an excellent option for many audio applications.
