Overview
Description
The SmartBeat™ DA7402 is a high-performance, ultra-low-power stereo hi-fi codec. Featuring Dialog’s custom digital hybrid active noise cancellation (ANC) technology, it offers stronger suppression of ambient noise over a wider range of frequencies for the best user experience in any environment.
With its integrated audio processor, the DA7402 delivers excellent audio performance including dynamic ranges for playback of 115 dB and sampling rates up to 384 kHz. It also offers 40 kHz audio bandwidth to support Hi-Res Audio. All this while consuming just 8.5 mW during stereo playback with ANC.
The DA7402 is available in a choice of compact packages to meet the needs of even the most space-constrained applications. Moreover, it is part of a family of pin-compatible codecs, making it easier for you to develop high-resolution headphones, headsets and earbuds to impress even the most demanding user. It combines industry leading audio and wideband hybrid digital ANC in a space-saving solution whose low power consumption could enable longer playback times.
