The CS4398 accepts PCM data at sample rates from 32 kHz to 200 kHz, DSD audio data, has selectable dig- ital filters, consumes little power, and delivers excellent sound quality. It also offers an optional path for direct DSD conversion by di- rectly using the multi-element switched capacitor array. Copyright © (All Rights Reserved) CS4398 ultibit lte r. Cirrus Logic reserves the right to modify this product without notice. This document contains information for a new product. The Analog Devices chip does the sample rate converting, and then sends the higher rate data to the CS4398 for conversion to an analog signal.Īlso if you want 24 bit stuff on your computer you'll have to get a hold of high quality SACD rips or something else in that. The Ultra Micro DAC and Max DAC have both the AD1896 and the CS4398.

I'm not sure what the other higher end DACs use for their USB input. Also please take notice that the USB input on the Micro DACs uses the same TI PCM2902 USB to S/PDIF chip which is only compatible up to 16bit 48kHz. It smooths things over so that it sounds more tube like, very pleasant sounding yes but does not create instant SACD sound. Please note that the upsampling does not turn everything into a perfect 24/192 source. The Ultra Micro with the AD1896 chip up samples all incoming stuff to 24 bit 192kHz.

Which means that 16 bit 44.1kHz stuff (cds) would play fine. The home module does not up convert but the CS4398 is compatible with all common formats UP TO 24 bit 192kHz.
