Dialog Semiconductor plc (FWB: DLG), a provider of highly integrated
power management, audio and short range wireless technologies, today
announced its latest ultra low power audio CODEC, designed to provide
full range, high fidelity audio capture and playback to a variety of
portable devices and audio accessories.
Dialog's new DA7320 audio CODEC features a programmable Digital Signal
Processor (DSP) to offload audio software from the host processor. The
use of Dialog's audio algorithms has been market proven by leading
smartphone OEMs to help deliver a consistent and enhanced user
experience under a wide variety of use cases.
By using a multi-channel architecture that digitally mixes and routes
multiple audio streams, combined with programmable N-band parametric
equalisation (EQ) and Dynamic Range Compressor (DRC), Dialog's
technology ensures louder and cleaner audio delivery on headphone and
speaker peripherals. A psychoacoustic bass boost (PBB) can be enabled
for improved perceived low frequency response for playback on low cost
small form factor speakers.
DA7320 is the first release in a new family of products that will be
expanded to include third party branded audio software, such as noise
suppression, acoustic echo cancellation and microphone beamforming.
Udo Kratz, Senior Vice President and General Manager of Dialog's Mobile
Systems business group, commented, 'Dialog's new DA7320 delivers
natural, immersive audio to wired headphones, headsets, earpieces and
extremely small form factor speakers as demanded by the thinner products
that consumers increasingly want to use. The device's built-in
flexibility and multiple ways to connect audio has already resulted in a
reference design win for a broad-based platform coming to market in
The new audio CODEC uses a single supply voltage of just 1.6V, has an
ultra-low power consumption of 3.85mW and supports common sample rates
between 8 to 96kHz in master and slave modes. The DA7320 comes in a 64
pin BGA package with a 0.5mm pitch and has an operating temperature
range of -400C to +85oC. The product is sampling now.
