Provides premium sound and integrated protection features

TI announced the release of three new digital input Class D audio amplifiers. By using these amplifier products, high-resolution audio can be achieved in various smart home and voice-assisted applications.

In addition, by combining previously unseen features, real-time protection capabilities, and new tampering methods, it enables reduction of board space and overall Bill of Material (BOM) costs. These new products are suitable for use in personal electronic device applications of all power levels, including smart speakers, soundbars, TVs, laptops, projectors, and IoT.

TAS2770 15W Audio Amplifier – Improves Volume and Sound Quality, Simplifies Voice Capture

• Efficiently driving high-output peak power with small speakers: The TAS2770 is the first wide-power I/V sensing amplifier that provides state-of-the-art real-time speaker protection when used with TI Smart Amplifier algorithms.

This amplifier can monitor speaker operation and increase volume, while applications requiring small speakers can improve audio quality without changing the existing design.

• Voice command addition without audio design changes: The TAS2770 is the industry's first audio front-end (AFE) device to combine a digital microphone input with a powerful I/V sense amplifier. Since this device can capture voice and ambient acoustic information, echo cancellation and noise attenuation are possible for voice-assisted applications.

• Prevention of audio clipping and brownout: The TAS2770 monitors battery voltage and automatically reduces gain when the audio signal exceeds a set threshold to avoid clipping issues, and extends usage time by minimizing battery consumption without degrading sound quality.

TAS5825M Audio Amplifier – 192kHz Audio Processing for Smart Speakers

• Improved and protected system audio quality: By utilizing this device's 192kHz input sampling frequency and flexible integrated processing flow, high-resolution audio can be achieved with minimal engineering effort. In addition, the TAS5825M provides bass enhancement and overheat protection as a speaker.

• Simplified Echo Removal: The TAS5825M's dedicated serial audio interface data output provides ambient sound information to the application processor.

• Reduced Power Consumption: By utilizing the TAS5825M's unique hybrid mode modulation method, idle power loss and heat generation can be reduced without degrading sound quality.

TAS3251 Audio Amplifier – Improves Sound Quality and System Reliability

• High performance and feature integration: The TAS3251 is the first integrated digital input solution in an “all-in-one” single package that supports maximum output power and performance with 2x175W.

• Achieve reliable high-output audio: Flexible processing up to 96kHz is possible, and includes self-protection features such as cycle-to-cycle current limiting and DC speaker protection.

These Class D amplifiers are new additions to TI's premium audio amplifier product portfolio, enabling the design of systems that deliver high-quality sound for a wide range of applications, from automobiles to personal electronics and professional audio systems.
