AKM Launches AK5705 Low Power 4-Channel 32-bit A/D Converter

Asahi Kasei Microdevices (AKM) has developed the AK5705, a low power consumption 4-channel 32-bit A/D converter (ADC) with a built-in transimpedance amplifier in addition to a low-noise microphone amplifier. The new AKM the AK5705 ADC is connectable to current output sensors, supports a sampling frequency of 384kHz, and achieves a dynamic range of 109dB, while consuming 43% less power than existing AKM products. The built-in AC coupling capacitor significantly reduces the mounting area including external components.

Promoted every year by the market research firm Futuresource Consulting, Audio Collaborative 2019 full-day conference on November 7 was invaluable, with Futuresource's leading market analysts and researchers sharing some of the latest stats and trends on the topics in the agenda, combined with great panels and in-between keynotes. This is the third of my reports, originally published in The Audio Voice newsletter.

The audio industry was once again shaken to its foundations by Apple's announcements at the Worldwide Developers Conference (WWDC) 2017. The product updates and sneak peeks made at this Apple Special Event, on June 5, 2017, were extremely rich in surprising technology revelations, even though its implications might not become clear until a few weeks or months later. After all, the WWDC conference - a developer's conference - is traditionally where Apple builds the foundations for what will be its underlying short-term/long-term strategies, serving mainly to motivate developers and strategic partners.
