The TAS5615DKDR is a high-performance, digital-input, Class-D audio amplifier IC that requires very little external components and occupies minimal board space while still delivering up to 28W when powered by a 6.5V supply. The device utilizes a patented spread-spectrum switching technogy along with advanced digital modulation techniques to reduce audio distortion and EMI emissions. It offers an optimized solution for high-end audio applications. This device is ideal for powering midrange and high-frequency loudspeakers, as well as applications such as TVs, home theatre systems, desktop PCs, and active speakers.

TAS5615DKDR is powered by a single 6.5V supply and can deliver up to 28W of power in a 4Ω load. The TAS 5615DKDR features a low-temperature differential minimum measurable performance accuracy (LTDMPA) of 94dB and low total harmonic distortion and noise (THD+N) of 0.004%. The device is also capable of output power headroom of up to 10dB, allowing it to deliver clean and dynamic audio at much lower frequencies than traditional amplifiers. The integrated low-pass filter also helps to eliminate ban resonance, eliminating the need for separate external components. In addition, the device provides a comprehensive set of protection features, including short-circuit protection, soft-start, output disabling, and thermal shutdown.

At a high level, the TAS 5615DKDR can be divided into three blocks: the power stage, the modulation circuit, and the post-processing block. The power stage consists of two high-side power transistors, two low-side power transistors and two gate drivers. The gate drivers drive the transistors, providing the voltage/current needed to power the speaker. The modulation circuit consists of a continuously adjustable transconductance amplifier, a phase-shifter, a control system, and a high-speed clock buffer. The transconductance amplifier takes the audio input signal, amplifies it, and adjusts the gain and offset of the signal. The phase-shifter then shifts the audio signal in phase, allowing the switching MOSFETs in the power stage to operate in the correct phase.

The post-processing block helps to further refine the audio signal. It consists of a digital low-pass filter, which helps to minimize audible distortion and a linear equalization stage, which enables the speaker to provide a rich, detailed sound. The digital low-pass filter also helps to reduce out-of-band noise, allowing the amplifier to produce clean, stable output signals. Finally, the output gain and level adjust feature allows the user to customize the output level and limit the amplifier’s peak output power.

Overall, the TAS5615DKDR is an ideal solution for high-end audio applications that require low distortion, high power, and minimal board space. Its combination of low-power components and advanced digital modulation techniques makes it an excellent choice for powering midrange and high-frequency loudspeakers, as well as applications such as TVs, home theatre systems, active speakers, and desktop PCs.
