DACs deliver exceptional audio fidelity for mobile devices

03-05-2019 | Mouser Electronics | Semiconductors

Mouser now stocks CS43131 and CS43198 high-performance MasterHIFI DACs from Cirrus Logic. Supporting sampling frequencies up to 384kHz, the 32-bit stereo audio DACs produce exceptional audio quality in a wide variety of applications including smartphones, laptops, tablets, powered speakers, portable media players, digital headphones, and home theater systems.


The DACs provide exceptional reproduction of high-bandwidth, high-resolution digital audio sources without depleting battery life. Built on an enhanced delta-sigma oversampling DAC architecture that comprises auto mute detection and low clock jitter sensitivity, the DACs help to filter out unwanted noise for ultra-high-quality music playback.


The CS43198 is a next-generation, low-power audio DAC with pseudodifferential stereo analog output, while the CS43131 joins the DAC with a high-fidelity headphone amplifier and integrated high performance, ground-centered stereo headphone outputs. Both DACs produce up to 2VRMS output and feature headphone detection, mono mode support, integrated PLL, and DSD path support. The devices’ integrated PLL allows maximum clocking flexibility, while Popguard technology removes output transients in power-down or power-up events.


The DACs are supported by the CDB43131K and CDB43198K evaluation kits. Both evaluation kits comprise a USB cable, evaluation board, and HDR measurement board. The boards connect to a host adapter via I2C interface, supporting communication with a smart codec. The evaluation kits offer configurable serial audio headers, USB audio module capability, and WISCE I2C-based software control. The CDB43198K evaluation kit also provides headphone and line audio outputs.
