More Boom, Less Room: Audio Solutions for Personal Electronics

Analog Devices audio solutions harness technological breakthroughs such as Dynamic Speaker Management (DSM) to deliver more: more volume, more bass, and more quality than standard Class D amplifiers, neatly packaged into smaller-than-ever micro speaker designs. DSM smart amplifiers combine high-performance current and voltage (IV) sense amplifiers with a patented algorithm to enable up to a 2.5× increase in loudness (sound pressure level) while significantly improving bass response. Ultra low power output makes these micro speaker audio solutions ideal for personal electronics applications, from gaming to smartphones.

Ultra Low Power MCUs and IoT Security

ADI’s microcontroller units (MCUs) for the IoT combine the biggest embedded memories in their class with ultra low power technology so you can design smarter and more secure IoT products without running out of code space or battery life. Our innovative hardware and deep learning models bring artificial intelligence (AI) to the edge, enabling functions such as battery authentication and interconnectivity within the IoT, all using just microjoules of energy.

ADI’s secure authentication ICs for the IoT employ hardware-based embedded security to achieve low cost IP protection and trusted operation. Our turnkey solutions provide a core set of fixed-function crypto features for ease of implementation. In our physical unclonable function (PUF)-based ChipDNATM secure authenticators, each IC’s unique, embedded key is based on a PUF, making it immune to all known invasive attack tools and capabilities.
