CS43198

General Description

The CS43198 is a high-performance, 32-bit resolution, stereo audio DAC that supports up to 384-kHz sampling frequency

with pseudodifferential analog outputs. The advanced 32-bit oversampled multibit modulator with mismatch shaping

technology eliminates distortion due to on-chip component mismatch. Proprietary digital-interpolation filters support five

selectable filter responses with pseudo-linear phase and ultralow latency to minimize pre-echos and ringing artifacts. An

on-chip programmable filter is available for further response customization. Other features include volume control with

0.5-dB steps, wideband flatness mode support, and digital deemphasis for 44.1-kHz sample rate.

The patented on-chip DSD processor preserves audio integrity by allowing signal processing such as volume control and

50-kHz Scarlet Book recommended filtering to be applied directly to the DSD stream without an intermediate decimation

stage. Additional features like volume matching and channel mixing enable seamless transition between DSD and PCM

playback paths. Direct DSD Mode is also provided to bypass the DSD processor.

The CS43198 accepts I2S, right-justified, left-justified, and TDM-format PCM data at sample rates from 32 to 384 kHz. The

industry-standard high-speed I2C interface capable of up to 1-MHz operation provides easy configuration control. An

integrated PLL allows for maximum clocking flexibility in any system. Popguard® technology eliminates output transients

upon power-up or power-down events.

The CS43198 is available in a commercial-grade 42-ball WLCSP or 40-pin QFN package for operation from –10°C to

+70°C.
