According to the company, TI is the first in the industry to provide both integrated and non-integrated smart amplifiers, giving engineers a broad range of design options.
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 characterisation 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 5.7W output power into 4Ω and 3.8W into 8Ω at 4.2V.
- Low Idle-Channel Noise (ICN) simplifies designs: 15.9µV 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 maximises battery life. User-specified boost control helps customise 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.
TI offers a range of intuitive design tools for the TAS2555 smart amplifier to speed time-to-market and simplify evaluation. Along with the PurePath Console 3 software suite, TI offers a comprehensive EVM and a learning board tool for speaker evaluation. The TAS2555YZEVM is available for $149 from the TI store.
The TAS2555 smart amplifier is available now in a 3.47×3.23mm, 42-ball WCSP and is priced at $2.50 in 1,000 unit quantities.
