Linear audio amplifiers are essential components in audio systems of all types. Linear amplifiers are usually categorized as Class A, B, AB, D, G, H and S, with each type having its own set of characteristics and advantages. Class AB linear amplifiers are generally accepted as the industry standard for audio applications due to its low input power requirement and high power capability.

The TS4871EIDT is a monolithic dual-mode Class AB linear audio amplifier designed for a wide range of audio applications. It occupies a single 7-pin SOT-23 package and contains temperature compensation, over-temperature protection and over-voltage protection. It has a low portable audio battery drain when connected to a 3V DC supply. The TS4871EIDT integrates a maximum output power capability that enables it to operate as both amplifier and voltage follower in portable audio applications.

The working principle of the TS4871EIDT is based on the classic Class AB push-pull audio amplifier configuration. It consists of two symmetrical transistors connected in a complementary push-pull configuration. Each transistor (NPN and PNP) amplifies one half of the input signal, adding In-phase and Out-of-phase power components to the amplified output. To ensure the highest fidelity, TS4871EIDT is designed with an optimized bias current for maximum linearity and low distortion.

The applications of the TS4871EIDT include portable audio systems, multimedia speakers, PC sound cards, cell phones and other communications products. The integrated temperature compensation and over-temperature protection features allow the amplifier to operate in harsh environments. The low input power requirement makes it ideal for low frequency audio applications.

The TS4871EIDT has a wide range of advantages over other linear amplifiers, such as its high efficiency, low distortion, low power consumption, low voltage operation and high power capability. It is also designed with a low input power requirement, which makes it well suited for low power audio applications. In addition, the integrated temperature compensation and over-temperature protection features make it suitable for harsh environmental conditions.

In conclusion, the TS4871EIDT dual-mode Class AB audio amplifier is an excellent choice for audio applications. It provides superior sound quality with low distortion, high efficiency, low power consumption and low voltage operation. In addition, its integrated temperature compensation and over-temperature protection features make it suitable for a variety of low power audio applications in harsh environments.
