CS43198 - Cirrus Logic

CS43198 32-Bit High-Performance DAC

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 select.
