Cirrus Logic CS431xx High-Performance DACs
Cirrus Logic CS431xx High-Performance DACs are 32-bit resolution stereo audio DACs that support up to 384kHz sampling frequency. These DACs come with integrated low-noise ground-centered headphone amplifiers (CS43131) and pseudo-differential analog outputs (CS43198). The integrated ground-centered stereo headphone amplifiers can deliver more than 30mW into 32Ω load or 5mW into 600Ω load per channel at full performance. The CS431xx DACs eliminate distortion due to on-chip mismatch by utilizing an advanced 32-bit oversampled multi-bit modulator with mismatch shaping technology. These DACs minimize pre-echos and ringing artifacts by using proprietary digital-interpolation filters that support five selectable filter responses with pseudo-linear phase and ultra-low latency.
The CS431xxx DACs feature enhanced ΔΣ oversampling DAC architecture, headphone detection, integrated PLL, mono mode support, and direct DSD path support. These DACs accept I2S, left-justified, right-justified, and TDM-format PCM data at sample rates from 32kHz to 384kHz. The high-speed I2C interface provides easy configuration control with up to 1MHz operation.
CS431xxx DACs consist of an integrated PLL that allows maximum clocking flexibility in any system and Popguard® technology that eliminates output transients upon power-up/-down events. These DACs operate within a -10°C to +70°C temperature range and are available in a 42-ball WLCSP or 40-pin QFN package. Typical applications include tablets, smartphones, powered speakers, home theatre systems, and pro audio.
