Chapter 2 Audio converter system Descriptions
2.1 Feature Summary
The DFS1000R System is a complete analog-to-digital converter for
digital audio systems. It performs sampling, analog to digital conversion, and anti-
alias filtering, generating 24-bit values for both left and right inputs in serial form at
sample rates up to 200 kHz per channel.
The DFS1000R System uses a 5th-order, multi-bit Delta-Sigma modulator followed
by digital filtering and decimation, which removes the need for an external anti-alias
filter. The DFS1000R is ideal for audio systems requiring wide dynamic range,
negligible distortion and low noise, such as set-top boxes, DVD-karaoke players,
DVD recorders, A/V receivers, and automotive applications.
