Cirrus Logic CS43198-CWZR

Voltage - UnbufferedI²S1.66V ~ 1.94V-10°C ~ 70°C

Overview

The CS43198-CWZR is a next generation, low power audio DAC that provides a superior system-level audio performance without draining battery life. This IC minimizes board space requirements while enabling performance and features to drive design differentiation. The CS43198-CWZR 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. To minimize pre-echos and ringing artifacts, the CS43198-CWZR is designed with proprietary digital-interpolation filters that support five selectable digital filter responses. Filtering options include low group delay with pseudo-linear phase and a fast or slow roll-off. 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. Volume matching of the analog output levels and channel mixing enable a seamless transition between the DSD and PCM playback paths. The CS43198-CWZR is available in a 40-pin QFN or a 42-ball WLCSP packages.
