TAS5830RHBR 概要
A Class-D audio amplifier is a switching amplifier that uses pulse-width modulation (PWM) to drive the output stage, achieving high efficiency (typically >85%) compared to linear amplifiers. The TAS5830RHBR integrates a closed-loop feedback architecture that reduces distortion and improves power supply rejection, ensuring high-fidelity audio reproduction. The Class-H algorithm dynamically adjusts the supply voltage to the output stage, further enhancing efficiency and reducing heat dissipation, which is critical for compact consumer electronics.
Key features include a digital input interface (I2S), integrated closed-loop feedback, advanced Class-H algorithm, and high output power of 2x50W into 4 ohms. The device also supports multiple output configurations and includes comprehensive protection features such as overcurrent, overtemperature, and undervoltage lockout. The RHB package (VQFN-32) provides excellent thermal performance, enabling reliable operation in space-constrained designs.
Technically, the TAS5830RHBR uses a high-performance digital audio processor that supports sample rates up to 192 kHz and 24-bit resolution. The closed-loop architecture ensures low total harmonic distortion (THD) and high signal-to-noise ratio (SNR), meeting the demands of high-end audio systems. The device also features a programmable gain and multiple I2C control options, allowing designers to optimize performance for specific applications.
Typical applications include soundbars, home theater receivers, active speakers, and automotive audio systems. The digital input simplifies connection to digital audio sources, while the high efficiency reduces the need for large heatsinks, enabling compact product designs.
When designing with the TAS5830RHBR, ensure proper PCB layout with adequate ground planes and thermal vias to manage heat dissipation. The device requires a well-regulated power supply and careful attention to output filter design to minimize EMI and ensure stable operation.

設計ノート
The TAS5830RHBR can dissipate significant power at high output levels. Ensure adequate thermal management by using a solid ground plane and thermal vias under the exposed pad of the VQFN-32 package. For 2x50W output, consider a heatsink or forced airflow to keep junction temperature within limits.
Place decoupling capacitors close to the PVDD, AVDD, and DVDD pins to minimize noise. Use a 10uF ceramic capacitor for PVDD and 1uF for AVDD/DVDD. Route the I2S and I2C traces away from the output stage to avoid interference. Follow the layout guidelines in the TI evaluation module documentation (SLAU965).
Ensure the power supply can handle the peak current demands of the amplifier. Use a well-regulated supply and consider bulk capacitance to prevent voltage droop. Also, design the output LC filter carefully to match the speaker impedance and minimize EMI. Refer to the datasheet for recommended filter values.
