AD1955ARSZ

音频数/模转换器 IC IC 24 Bit 192kHZ 123 Db DNR w/SACD

PRODUCT OVERVIEW  

The AD1955ARSZ AD1955 is a complete, high performance, single-chip, stereo  digital audio playback system. It is comprised of a multibit sigmadelta  modulator, high performance digital interpolation filters,  and continuous-time differential current output DACs. Other  features include an on-chip clickless stereo attenuator and mute  capability, programmed through an SPI compatible serial control  port. The AD1955ARSZ AD1955 is fully compatible with all known DVD audio  formats including 192 kHz as well as 96 kHz sample frequencies  and 24 bits. It is also backward compatible by supporting 50 μs/  15 μs digital de-emphasis intended for “redbook” compact discs,  as well as de-emphasis at 32 kHz and 48 kHz sample rates.
