TAS5825MRHBR

The Texas Instruments TAS5825MRHBR is an active Class-D Smart Audio Amplifier designed for high-efficiency audio amplification. It supports multiple output configurations, delivering up to 38W in stereo mode (2x38W at 8Ω, 24V, THD+N=10%) or up to 65W in mono mode (1x65W at 4Ω, 22V, THD+N=10%).

This amplifier features a digital input architecture and supports a wide range of sample rates from 32kHz to 192kHz, including I²S, LJ, RJ, or TDM interfaces. It operates with a power stage supply voltage ranging from 4.5V to 26.4V and an analog supply voltage from 4.5V to 26.4V. The device boasts excellent audio performance with low THD+N (≤0.03% at 1W, 1kHz) and a high SNR (≥110 dB A-weighted).

Key features include high power efficiency (>90%), low quiescent current (<20 mA at 12V PVDD), and flexible processing capabilities such as 3-band DRC, equalization, and spatializer effects. Integrated self-protection features like over-current, over-temperature, and under/over-voltage lock-out enhance reliability. The TAS5825MRHBR is housed in a compact 5mm x 5mm VQFN package, suitable for surface mounting and reducing the need for external passive components like inductors and bulky capacitors.

Its design considerations include flexible power supply configurations and software control via I²C, making it suitable for applications in home audio, soundbars, and other consumer electronics requiring efficient and high-quality audio amplification.
