TDF8599BTH/N1,518 Application Field and Working Principle

The TDF8599BTH/N1,518 is a linear amplifier belonging to the class of audio amplifiers. Its main application areas include domestic audio-visual systems, medical electronics, communications, and audio instrumentation. The device is especially suitable for use in mobile phone handsets, with excellent noise suppression and low power consumption.

Overview

The device, which is bi-directional, has a maximum rated power of 1.8 V and can operate in a range from 1V to 3.1V. It has very low power dissipation and RF sensitivity, with an output impedance of 470 Ω and a total harmonic distortion (THD) of 0.002%. The amplifier comes with a mute/unmute pin that can be used for dynamic power control and a standby mode for low power applications.

Working Principle

The amplifier operates on the principle of amplifying incoming signals from an external audio source to the desired output level. The amplifying process is done by converting the input signal into electrical energy that is in turn amplified by the amplifier. For this purpose, the amplifier has five main function blocks – differential input stage, voltage amplifier, driver stage, emitter loop, and output stage.

The differential input stage amplifies the input signal and the voltage amplifier amplifies the input signal with a certain amount of gain. The driver stage then amplifies the voltage signal to the power required for the output stage. The emitter loop takes in the amplified signal from the driver stage and further amplifies it. The output stage takes the amplified signal from the emitter loop and delivers it to the output terminal of the amplifier.

Features and Benefits

The main features and benefits of the TDF8599BTH/N1,518 amplifier include its high power, low power consumption, low impedance, low THD, and very low noise level. The amplifier is designed for use in mobile phone handsets and other audio-visual systems, providing excellent audio performance and sound quality.

The amplifier offers a very low current consumption and is able to operate in a full power mode without any noise or RF sensitivity issues. This is further enhanced by the mute/unmute pin, allowing dynamic power control of the device. In addition, the device features a standby mode which allows for lower power consumption when the device is not in use.

Conclusion

The TDF8599BTH/N1,518 amplifier is a bi-directional linear audio amplifier that can provide high power and excellent sound quality in a wide range of applications. Its features include low power consumption, low impedance, low harmonics, and very low noise level.
