TAS5827RHBR - 43W Stereo Digital Class-D Amp | Texas Instruments
MPN： TAS5827RHBR ✓ 啟用中TAS5827RHBR 概覽
A Class-D amplifier is a switching amplifier that uses pulse-width modulation (PWM) to achieve high efficiency, often exceeding 90%, compared to linear amplifiers. The TAS5827 integrates a closed-loop architecture that reduces distortion and improves power supply rejection, making it suitable for high-fidelity audio systems. The digital input interface accepts I2S, TDM, and other digital audio formats, simplifying system design by eliminating the need for external DACs.
Key features include a 43-W output power per channel into 4-ohm loads, integrated audio processor with biquad filters and dynamic range compression, and Class-H control that optimizes power supply voltage for efficiency. The device also supports multiple switching frequencies and offers cycle-by-cycle current limit protection. Its closed-loop design ensures low THD+N and high signal-to-noise ratio, critical for premium audio performance.
The TAS5827 uses a digital audio processing core that can be configured via I2C or hardware control mode. In hardware mode, switching frequency, analog gain, BTL/PBTL mode, and current limit threshold are set via pins, eliminating the need for software driver integration. This flexibility makes it easy to deploy in systems where firmware development is not desired.
Typical applications include smart speakers, soundbars, home theater systems, and automotive audio. The high efficiency reduces heat dissipation, enabling compact designs without large heatsinks. The integrated audio processor allows designers to implement EQ, crossover, and dynamic range control without external DSP.
When designing with this device, ensure proper PCB layout with adequate ground planes and decoupling capacitors near the power pins. The thermal pad must be soldered to a copper area for heat dissipation. Also, consider the input signal format and configure the device accordingly for optimal performance.

設計說明
Ensure proper PCB layout with adequate ground planes and decoupling capacitors near the power pins. The thermal pad must be soldered to a copper area for heat dissipation. Use multiple vias to connect the thermal pad to the ground plane for improved thermal performance.
The TAS5827RHBR operates from 4.5V to 26.4V. Use a stable power supply with sufficient current capability. Place a 10uF ceramic capacitor close to each PVDD pin and a 0.1uF capacitor for high-frequency decoupling. Ensure the power supply can handle peak current demands during high-output conditions.
Do not exceed the maximum supply voltage of 26.4V. Ensure the digital input signal format (I2S/TDM) is correctly configured. In hardware control mode, set the switching frequency and gain via pins. Verify the I2C address and control settings to avoid misconfiguration.
