The TAS5414ATDKDRQ1G4 is a member of the TI Audio Amplifier family, which is specifically designed to provide design engineers with extremely efficient operation, low cost and excellent linear performance. The amplifier integrates a single-ended, low-power Class D power stage with an input buffer, selectable gain and on-chip temperature sense capability for maximum reliability. The device is ideal for driving very low-power loads such as mobile phones, small loudspeakers and other portable audio applications.

The device is an integrated single-ended Class D amplifier with integral high-voltage PWM modulator for high-efficiency audio applications. The device includes a low-noise input buffer, a high power-output stage, selectable low-power enable and low-power shutdown, integrated temperature monitoring capability and enhanced pulse density modulation (PDM) solutions. The device delivers up to 200 mW into 8 ? speakers and consumes a low 3.2 mW at 1.5 V over a wide temperature range. The device is designed to support a wide range of audio frequencies and dynamic range requirements, including high-fidelity audio, in mobile phones, headsets, portable media players and other battery-operated applications.

The device integrates a single-ended, low-power Class D power stage with an input buffer, selectable gain and on-chip temperature sense capability for maximum reliability. The buffer is designed to provide excellent linear transfer characteristics, characterized by a low source impedance, low distortion, low noise, and excellent linearity from DC to HF. The Class D power stage of the device utilizes discrete components and can deliver up to 200 mW into 8 ? mode loads. The amplifier is designed to operate with low quiescent current in a stable, linear manner over a wide range of power supply and load conditions. Furthermore, the amplifier is designed to optimize efficiency and power dissipation at low output powers and higher output currents.

The TAS5414ATDKDRQ1G4 is an amplifier that is primarily designed for portable consumer audio applications in battery-powered systems. It is optimized for low-voltage operation from a single supply, eliminating the need for dual-voltage supplies. The device provides an efficient and reliable solution for audio amplification that is immune to electric-field interference and EMI noise, delivering superior quality audio performance with a high degree of power savings for most consumer applications.

The device works by amplifying the audio signal that comes in through the input. The buffered amplifier converts a low-voltage input signal into a high-voltage output signal with a much higher amplitude. The power stage then takes this higher voltage signal and amplifies it further, driving the speaker output with the desired power. The amplifier utilizes an advanced pulse density modulation technology to achieve the highest efficiency and the lowest distortion. The device is also equipped with a low-power shutdown, which enables the amplifier to switch off whenever the audio signal is low, thus saving power and reducing the overall system current consumption.

The TAS5414ATDKDRQ1G4 is a current-mode amplifier solution optimized for low-power portable audio applications. With its low power consumption, highly efficient operation and excellent linear performance, the device provides an ideal solution for driving low-power loads such as mobile phones, small loudspeakers and other portable audio applications.
