High-end stereo audio ADCs for prestige
markets
Wolfson Microelectronics (LSE:WLF.L) has launched a new family of high performance 24-bit stereo ADCs for high performance recordable media devices for prestige consumer markets.
Mixed signal IC specialist Wolfson Microelectronics (LSE:WLF.L) today launches a new family of high performance 24-bit stereo ADCs for high performance recordable media devices, such as recordable DVD Players and personal video recorders, and A/V amplifiers, as well as high end sound cards and studio audio processing equipment Utilising advanced mixed signal techniques in multi bit sigma-delta design, and a proprietary cascade topology, WM8780/1/5/6 maximise signal to noise ratio, up to 111dB, resulting in clean, accurate sound in compact and convenient surface mount packages

Wolfson's high-performance stereo digital-analogue conversion technology is at the heart of two new CD players introduced by hi-fi specialist Rega Research.
Stereo DAC supports Direct Stream Digital
Wolfson Microelectronics has unveiled its first stereo DAC with support for the Direct Stream Digital (DSD) audio data format.
A choice of single-ended or differential analogue inputs allows designers to achieve an optimal balance of audio performance, system cost and design effort.
Both input-types are available in hardware and software controllable variants.
The WM8780 and WM8781 have single ended inputs and achieve signal to noise ratio of 107 dB and total harmonic distortion -98dB.
Designed with differential inputs, the WM8785 and WM8786 reach 111 dB SNR and a total harmonic distortion -102 dB.
Capable of 24-bit high-resolution sampling at frequencies from 8 kHz to 192 kHz, the digital output audio word length is configurable from 16 to 32-bit and delivered as a PCM output.
Wolfson's proprietary low order modulator minimises jitter effects, and a selectable high pass filter is available to remove residual DC offsets.
The devices support a TDM bus, providing designers with extra flexibility to build advanced audio processing equipment, including complex multi-channel studio equipment or surround sound systems.
The WM8780 is packaged in a very low pin-count 16-pin SOIC for optimum board space utilisation and low number of interconnects.
WM8781, WM8785 and WM8786 are available in small outline 20-pin SSOP packages.
