Introduction

As one of the popular analog and digital components in the audio industry, the TAS5624ADDVR amplifier is a high performance and low distortion Digital Audio Power Amplifier. It integrates a high efficiency I2C controlled Class D amplifier with a Variable Reluctance (VR) technology in an very compact size, making it ideal for various professional and consumer audio applications.

Application

The TAS5624ADDVR amplifier is designed for applications such as pro audio and broadcast, professional PA systems, home audio, plasmas and LCD TVs, automotive Sound Systems, digital sound processors, portable multimedia players and docking stations.

Features & Benefits

The TAS5624ADDVR amplifier comes with a comprehensive range of features and benefits, such as integratedboost switching regulators, minimal input/output mismatch, and fully digital I2C interface. These features make it ideal for various audio applications, as it is easy to use, efficient, and provides a high performance output.The digital Boost Switching regulator also provides power savings and improved efficiency, while the VR technology provides an adjustable output voltage and current from 0.5V to 30V and up to 4.5A. This allows for a wide range of output power capabilities, from a few watts to hundreds of watts.

Design Considerations

For optimal performance, the TAS5624ADDVR amplifier should be selected carefully, as it is dependent on the power level, the power supply, the particular circuit topology, the efficiency, and the desired input/output interface.The amplifier is also designed for use with a compatible input/output interface, typically balanced analog, digital, or I2S/SPDIF. It also requires an appropriate power supply, such as a Lead-Acid battery, Lithium Polymer battery, or a DC power supply.

Working Principle

The working principle of the TAS5624ADDVR amplifier is based on the Variable Reluctance technology. This technology works by creating an adjustable magnetic field in relation to the voice-coil in the VR component. This magnetic field then drives the voice-coil to move, and thus produces variations in the audio signal strength.The audio signal is then amplified by the signal amplifier, and the signal is further amplified by the Class D amplifier into the desired output power level. The I2C interface is used to control the frequency, impedance, and sensitivity of the VR component, as well as the output power level of the Class D amplifier.

Conclusion

The TAS5624ADDVR amplifier provides a high-performance and low-distortion Digital Audio Power Amplifier, ideal for industrial and consumer audio applications. It integrates a high efficiency I2C controlled Class D amplifier with a Variable Reluctance technology in a very compact size, and comes with a comprehensive range of features and benefits. The working principle of the amplifier is based on the Variable Reluctance technology, and it requires an appropriate power supply, such as a Lead-Acid battery, Lithium Polymer battery, or a DC power supply.
