Mouser adds DACs from Cirrus Logic

The CS43131 and CS43198 digital analogue converters (DACs) form Cirrus Logic, deliver audio fidelity for mobile devices. The DACs are now available at Mouser.

The MasterHIFI DACs support sampling frequencies up to 384kHz. The 32-bit stereo audio DACs can be used in smartphones, tablets, laptops, powered speakers, digital headphones, portable media players, and home theatre systems.

The Cirrus CS43131 and CS43198 DACs reproduce high-bandwidth, high-resolution digital audio sources without draining battery life, explains Mouser. Built on an enhanced delta-sigma oversampling DAC architecture that includes auto mute detection and low clock jitter sensitivity, the CS43131 and CS43198 help to filter out unwanted noise for high-quality music playback.

The CS43198 is a low-power audio DAC with pseudo-differential stereo analogue output. The CS43131 combines the DAC with a high-fidelity headphone amplifier and integrated high performance, ground-centred stereo headphone outputs. Both DACs deliver up to 2V RMS output and feature headphone detection, mono mode support, integrated PLL, and direct stream digital (DSD) path support. They also have integrated PLL which enables maximum clocking flexibility and Popguard technology eliminates output transients in power-down or power-up events.

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