Best-in-class amplifier with integrated speaker protection is supported by a new software suite to accelerate development

11/20/2015

Texas Instruments (TI) introduced a low-power smart amplifier that allows designers to develop next-generation smartphones with industry-leading audio quality at peak volumes while maximizing battery efficiency. The TAS2555 Class-H audio amplifier with integrated speaker protection uses back electromotive force and low power of 5.7 W to produce bigger sound from small devices. TI is the first in the industry to provide both integrated and nonintegrated smart amplifiers, giving engineers a broad range of design options. For more information on the new audio amplifier, visit www.ti.com/tas2555-pr.

The TAS2555 is also the first low-power amplifier supported by the PurePath™ Console 3 software suite, which gives both advanced and beginner designers a path to meet diverse system requirements. The solution takes the guesswork out of speaker characterization and includes easy-to-use tools for tuning and integration into end products, thus accelerating time to market for smartphones, tablets and other audio-enabled portable electronics.

Key features and benefits of the TAS2555 smart amplifier

  • Louder and clearer audio: Offers 5.7-W output power into 4 Ω and 3.8 W into 8 Ω at 4.2 V.
  • Low idle-channel noise (ICN) simplifies designs: 15.9-µV ICN eliminates audible speaker noise when using the smartphone in a receiver or pause mode and also eliminates the need for external components.
  • Integrated multilevel Class-H boost converter and automatic gain control: Dynamically adjusting audio output during periods of low battery voltage maximizes battery life. User-specified boost control helps customize boost on/off based on end-equipment power profile requirements.
  • Reduces development time: Use any processor with an I2S output to enable on-chip speaker protection. This greatly reduces porting and integration time, enabling end equipment manufacturers to get to market faster.
