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.
It was designed to provide improved scan rates for high-speed scanners as well as the next generation multifunctional peripherals.
"The flatbed scanner market continues to demand improved scan speeds and, as higher throughput rates become possible, for example with USB2, we expect demand for higher speed scanner products to surge ahead", said David Milne, Wolfson's Managing Director.
"At Wolfson we are excited by the opportunities we can serve with this excellent product, not only in scanners but also in the rapidly growing multifunction peripheral (MFP) market.
We know that every MFP customer now expects the same solid performance from a scanner integrated with a printer as he does from a standalone scanner.
We expect this fast AFE to be widely taken up in MFP applications".
Wolfson's AFE family also finds applications in products such as professional and large format scanners, check and lottery ticket scanners, medical imaging, barcode and waybill scanners and other applications which use CCD and CIS image sensors.
The WM8199 device is a 16bit, 20Msample/s convertor front end for use with CCD or CIS image sensors.
Operable in either single, dual or three channel modes the AFE is easy to interface to, with reset level clamping, correlated double sampling, programmable gain and offset adjust functions.
The WM8199 allows users to take advantage of the higher throughput rates of new interface standards such as USB2 and IEEE 1394.
The architecture and firmware setup protocols offer an easy migration route from other members of Wolfson's family of single-chip AFEs.
