Smartphone amplifier is 'world's smallest'

The CoolFlux DSP, a high-efficiency class-D amplifier with current sensing, and a DC/DC converter are integrated into a single chip. According to the company, the TFA9897 offers the lowest latency protection available, making it capable of competing with other amplifiers that feature higher power ratings. The amplifier is a turn-key solution, compatible with all platforms and is easy to integrate.

Since NXP introduced the world’s first smart amplifier in 2012, the majority of leading smartphone manufacturers have adopted NXP speaker-protection solutions to improve the sound quality and volume provided by their devices. In just two and a half years, the company has shipped more than 150m smart-amplifier ICs.

The consumer demand for high-quality sound in smartphones is increasing the demand for smart amplifiers. With its smart amplifiers, NXP addresses the acoustic challenges created by thinner and smaller handsets as well as the repositioning of the speakers on the front of the phones.

“Over the past year, smart amplifiers have become the standard for premium smart phones. All top 15 smartphone makers use some form of speaker protection,” commented Shawn Scarlett, Marketing Director, Mobile Audio Solutions, NXP Semiconductors. “NXP is the clear market leader in smart amplifiers. We ship to 13 of the top 15 OEMs, including all of the top 10 OEMs in China. Our solutions can be found enhancing audio in the most sought after phones on the market today.”
