WM8718SEDS/V - 24-Bit Stereo Audio DAC | Cirrus Logic
Cirrus Logic WM8718SEDS/V is a 24-bit differential stereo digital-to-analog converter with volume control, supporting audio processing up to 192 kHz and digital audio through an I2S interface. The device is supplied in a 20-SSOP package for surface-mount assembly. Its combination of differential outputs, integrated digital volume control, and high-resolution conversion makes it suitable for professional audio, consumer audio, communications equipment, and multimedia playback systems.
A DAC is a digital-to-analog converter, a signal-conversion integrated circuit that transforms sampled digital audio into an analog voltage suitable for amplification and loudspeaker output. Within the broader semiconductor hierarchy, the WM8718SEDS/V belongs to the ADC/DAC class of data-conversion ICs and ultimately to the integrated-circuit category. It provides the output-side conversion function in a digital audio signal chain, typically following a source, codec, decoder, or digital audio processor.
The manufacturer datasheet identifies the WM8718SEDS/V as a 24-bit DAC operating to 192 kHz with digital signal processing, I2S connectivity, differential stereo outputs, and volume control. These features distinguish it from basic fixed-output DACs: differential output architecture supports balanced audio routing, while integrated volume control allows output-level adjustment without relying exclusively on a separate analog attenuator. The I2S interface also provides a conventional connection to digital audio processors and application processors.
The 20-SSOP package supports compact, surface-mount PCB construction while exposing the required digital, analog, clock, and power connections. Because the converter handles both digital and analog signals, board implementation requires careful partitioning. The digital interface and clock signals should remain separated from the differential analog outputs, with the manufacturer’s recommended application circuit and pin description used as the basis for component placement and trace routing.
Typical uses include multichannel consumer-audio receivers, powered speakers, sound-bar signal paths, digital mixing consoles, portable listening equipment, and embedded audio systems that require a compact stereo DAC. The 192 kHz capability is useful when the source material and upstream signal path support that rate, although operating at the maximum rate generally requires correspondingly clean clocking, layout, and power delivery.
Designers should verify the required master clock, I2S word length, sample-rate configuration, output load, and external filtering against the manufacturer datasheet before layout release. Differential routing should be treated as a matched pair, and the analog return path should connect cleanly to the device ground reference. These controls help preserve channel balance and reduce distortion introduced by the PCB rather than by the converter itself.
This product page combines the exact manufacturer and distributor identifiers, organizes the documented conversion and interface capabilities, and adds application, comparison, replacement, and layout guidance. It is intended to help engineers narrow a DAC choice by resolution, sample rate, interface, package, output architecture, and assembly requirements before completing a production BOM.
