DACs deliver up to 2 VRMS output

The DACs deliver exceptional reproduction of high-bandwidth, high-resolution digital audio sources without draining battery life.

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 ultra-high-quality music playback

The CS43198 is a next-generation, low-power audio DAC with pseudo-differential stereo analogue output, while 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 2 V_RMS output and feature headphone detection, mono mode support, integrated PLL, and Direct Stream Digital (DSD) path support. The devices’ integrated PLL enables maximum clocking flexibility, while Popguard technology eliminates output transients in power-down or power-up events.

They are supported by the CDB43131K and CDB43198K evaluation kits.

Both evaluation 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.
