Dialog Semiconductor plc has unveiled a 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 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.
The new audio codec uses a single supply voltage of just 1.6 V, has an ultra-low power consumption of 3.85 mW and supports common sample rates between 8 to 96 kHz in master and slave modes. The DA7320 comes in a 64 pin BGA package with a 0.5 mm pitch and has an operating temperature range of -400 to +85°C. The product is sampling now.
