Volume matching of the analog output levels and channel mixing enable a seamless transition between the DSD and PCM playback paths. A patented on-chip DSD processor supports up to DSD256 in direct mode to preserve audio integrity by providing non-decimating volume control with soft ramp, and 50 kHz filtering as recommended by Scarlet Book.
Filtering options include low group delay with pseudo-linear phase and a fast or slow roll-off. To minimize pre-echos and ringing artifacts, the CS43198 is designed with proprietary digital-interpolation filters that support five selectable digital filter responses. The CS43198 features a high impedance of 600 Ω, a 130 dBA dynamic range, a THD+N rating of -115 dB, and inter channel isolation of >110 dB. This IC minimizes board space requirements while enabling performance and features to drive design differentiation.
The CS43198 is a next generation, low power audio DAC that provides a superior system-level audio performance without draining battery life.
