Cirrus Logic presents a three-member family of ADCs intended for hi-res digitization of analog sources, among other things.
A portion of vinyl enthusiasts buy a turntable purely to listen to records “live”. The same applies to tape recorders and – to a lesser extent – cassette decks. Another part of fans is purely interested in unique content still lying around on these analog music carriers. They prefer to convert their precious material to digital as soon as possible to avoid loss and further degradation. To accomplish that, a good ADC is needed. Chip manufacturer Cirrus Logic has designed the CD5302P, CS5304P and CS5308P for that purpose, all part of the company’s Pro Audio line. The last digit in the type number of each indicates the number of analog inputs, which then also immediately distinguishes the three members.
32 bit / 768 kHz
The new Cirrus Logic ADC’s are designed for use in devices such as digital mixers, USB audio interfaces, but certainly also for home audio, AV receivers, musical instruments and more. The maximum sample resolution is 32 bit / 768 kHz, with a differential input provided too. The ADCs use a fifth-order multi-bit sigma-delta modulator, followed by digital filtering and cleanup. The whole should result in a dynamic range of 126 dB for the CS5302P and 123 dB for the CS5304P and CS5308P. The new arrivals of Cirrus Logic will appear on the market later this year and undoubtedly showing up in numerous devices thereafter.
