12V smart amplifier delivers rich sound in portable devices

The TFA9892 is the industry’s first power amplifier capable of delivering a 12V boosted output, reaching above 7W of output power from a single cell battery, or up to 15W from a 12V supply.

With best-in-class power performance, the TFA9892 features smart speaker protection by sensing current, power, and temperature, thus allowing consumers to get the best audio quality performance out of the speakers while preventing damage.

“Delivering superior sound quality with acoustic perfection is important to NXP and we always strive to create solutions that complement the user experience,” said Chae Lee, senior vice president and general manager, secure interfaces and power business with NXP.

“As a leading supplier of smart audio solutions, the new TFA9892 is a testament to how NXP delivers exceptional long lasting audio experiences in portable and mobile consumer devices.”

The new TFA9892 comes with an embedded on-board DSP featuring an integrated speaker boost algorithm that provides tremendous improvements in bass and drums performance, reduces background noise and eliminates compression artifacts.

With enhanced audio performance, the TFA9892 provides exceptional power efficiency, enables louder sound capability and wider dynamic range on to an 8-ohm speaker. In addition, high efficiency can reduce battery consumption to enable longer playing and listening time.

With the TFA9892 NXP delivers best-in-class speaker protection algorithm enabling power delivery of up to more than 7.4W on 4.2V batteries with 1% Total Harmonic Distortion (THD) on 8-ohm and two watt rated speakers.
