Dialog Semiconductor has introduced the DA740x, a household of highly-integrated audio codec chips that ship energetic noise cancellation (ANC) for wi-fi headphones.
“This new, groundbreaking audio codec family is expected to significantly grow Dialog’s share in the expanding wireless headphone market,” mentioned Sean McGrath, senior VP & GM of Dialog Semiconductor’s connectivity and audio enterprise group. “The highly integrated design approach affords our customers superior ANC performance and audio quality with fewer external components and a footprint of less than six square millimeters making it suitable for even the smallest in-ear formfactors. The DA740x allows manufacturers to build higher quality, lower power products in smaller devices with a faster time-to-market.”
The household consists of three chips – the DA7402, a stereo excessive efficiency (HP) codec with ANC; DA7401, a mono HP codec with ANC; and DA7400, a stereo HP codec. Dialog has particularly designed every chip to handle completely different segments of the headphone market offering prospects with a one-stop-shop for optimizing their total mid and high-end product vary, the corporate famous.
The DA7402 helps hybrid, feedforward, and suggestions topologies, as much as 35 dB suppression, and affords devoted calibration and tuning instruments, all to assist digital ANC. With excessive efficiency playback and file paths, DA7402 is designed for top dynamic vary and minimal latency. The DA7402 affords one of many smallest digital ANCs available on the market, with half the facility consumption and twice the audio efficiency in comparison with right this moment’s main chip options making it superb for sport earbuds, hearables, true wi-fi stereo (TWS) earbuds, unified communication headsets and extra.
As a spinoff of the DA7402, the DA7401 is a high-performance mono ANC Codec designed for TWS and hearable purposes. It affords a 115 dB playback dynamic vary, 103 dB file dynamic vary, hybrid ANC and versatile clocking structure. The DA7400 gives related capabilities and was designed for client purposes that require hi-resolution, excessive efficiency audio, with out ANC.
Dialog’s DA740x household of audio codecs is being introduced through the ongoing Computex Taipei 2019.
