CS43130
General Description
The CS43130 is a high-performance, 32-bit resolution, stereo audio DAC that supports up to 384-kHz sampling frequency
with integrated low-noise ground-centered headphone amplifiers. 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. Other features include volume control with 0.5-dB steps and digital deemphasis
for 44.1-kHz sample rate.
The integrated ground-centered stereo headphone amplifiers are capable of delivering more than 30 mW into 32- load
or 5 mW into 600- load per channel. Proprietary headphone impedance detection enables wide-band impedance
detection for further digital post-processing. An internal stereo audio switch with true bypass supports an alternate analog
input path for interfacing with external audio sources to minimize the overall bill-of-materials cost and PCB area.
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.

The CS43130 accepts I S, right-justified, left-justified, and TDM-format PCM data at sample rates from 32 to 384 kHz. The
2
industry-standard high-speed I C 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 CS43130 is available in a commercial-grade 42-ball WLCSP or 40-pin QFN package for operation from 10C to
+70C.
