Goodix Technology Launches Next Generation Smart Amplifier for Mobile Applications

Goodix Technology launched a new generation smart amplifier targeting mobile audio designs. The new TFA9865 device leverages a proprietary, fully digital architecture and advanced manufacturing processes to improve audio performance. With extremely compact dimensions of just 2.2x2.2mm², the TFA9865 audio amplifier establishes a benchmark for the audio industry, offering higher power efficiency, and enhanced sound volume with reduced noise.

Whether it is power amplifiers, vinyl reproduction preamplifiers, active crossover filters or, as in this case, small-signal circuits for a very wide range of applications, Douglas Self is one of those authors who consistently has produced reference works about technical audio. You may think that as a fourth edition, it would just be a refinement on the three editions that went before it but Self always adds new material and new insights to make it worthwhile to get this new book.

Oregon-based CUI Devices’ Audio Group announced the official launch of its new audio design services, with a team of sound specialists that are able to leverage advanced simulation tools and testing as well as decades of expertise to support developers and brands. Even for companies with their own in-house resources this level of support is able to optimize a range of audio parameters to specific system needs.

Designing Audio Circuits and Systems will have its 1st Edition published in April 2024, and advanced copies are being sent to reviewers, which includes audioXpress. Bob Cordell, wrote this new book as a comprehensive guide to audio circuits and systems design, beginning with analog audio basics, all the way through to in-depth design techniques for home and professional audio preamps, amplifiers, filters, equalizers, and even headphone amplifiers and DACs.

Linear Systems has reintroduced its most popular part, the LSK389, which the Silicon Valley company calls the industry’s first 100% noise tested, ultra-low noise (en = 1.3nV/√Hz (typ), f = 1.0kHz and NBW = 1.0Hz), monolithic dual, n-channel JFET. New test capability screens to a billionth of a ​volt (​nV​/√Hz) of noise now ensures that all ​LSK389s devices produce no burst (RTN or popcorn) noise and ​meet or exceed 1/f and broadband noise specifications.

Already manufacturing the most ‘Green’ amplifiers in terms of carbon footprint, Powersoft is now poised to shred efficiency agendas with the launch of a radical new redesign of its system-centric ArmoníaPlus control software. Uniquely loudspeaker-oriented, the new ArmoníaPlus interface mimics the real-world and the physical process of audio design with a workflow approach that is both simple to use and easy to navigate.

Following the announcement of their strategic alliance at InfoComm 2018, Atlona and Symetrix will take the first steps of a co-education initiative with a webinar. Scheduled from 10:30-11am on September 20, “Systems Design for Networked Audio” will outline the essentials of managing AES67 and Dante audio in a networked AV ecosystem, along with specifics on applying Atlona and Symetrix solutions to strengthen the overall infrastructure.
