WM8716SEDS/V - 24-Bit Stereo DAC | Cirrus Logic
부품 번호: WM8716SEDS/V ✓ 활성WM8716SEDS/V 개요
A DAC is a data converter that transforms digital audio samples into proportional analog voltages or currents. In the signal hierarchy, a stereo DAC sits between a digital audio source and an analog power amplifier. It converts compact disc, DVD, home-theater, set-top-box, digital-TV, and other digital-audio streams into a left and right analog pair suitable for downstream audio amplification. The WM8716SEDS/V belongs to the audio DAC, data converter, and integrated audio IC categories.
The WM8716SEDS/V provides two audio channels, 24-bit conversion, and operation at sampling rates up to 192 kHz. Its SPI-compatible control interface supports digital configuration of operating functions, while the integrated oscillator indicated by the product description provides a timing reference for the conversion system. A single 3.3 V to 5 V supply range simplifies mixed-voltage audio designs that also use modern digital source components.
The converter is intended for hi-fi and multimedia applications where channel separation, audio bandwidth, and direct digital control are important. At 192 kHz, it supports high-resolution audio playback while retaining a two-channel architecture. Its 28-pin SSOP package provides enough connections for stereo analog outputs, digital audio data, serial control signals, clocking, power, and ground without requiring a large surface-mount footprint.
Typical uses include CD and DVD players, home-theater receivers, set-top boxes, digital televisions, multi-channel audio systems, and other consumer playback equipment. The stereo DAC can sit between an audio processor or digital transport and an analog power-amplifier stage. Its 24-bit format and 192 kHz maximum rate are particularly useful when the source material exceeds conventional CD resolution and the downstream converter must preserve the original sample rate.
A critical design consideration is separating analog and digital return paths. Keep the stereo analog outputs away from SPI clock and data traces, connect decoupling capacitors close to the supply pins, and use the pin-description table in the Cirrus Logic datasheet when assigning PCB tracks. Designers should also verify the required master clock, digital interface mode, and analog output configuration in firmware before releasing a production layout.
This page combines the manufacturer specifications, verified distributor identification, a documented same-footprint replacement candidate, application guidance, and practical PCB considerations. It provides a focused engineering reference for evaluating the WM8716SEDS/V in stereo digital-audio systems while clearly separating known electrical facts from parameters that still require datasheet confirmation.

일반적인 애플리케이션
WM8716SEDS/V 적합 용도: 6 애플리케이션s: Home-Theater Stereo DAC, CD and DVD Player, Set-Top-Box Audio Output, Digital Television Audio, High-Resolution Audio Source, Multimedia Audio System.
Home-Theater Stereo DAC
The WM8716SEDS/V fits a home-theater playback path because it converts two digital audio channels with 24-bit resolution at sampling rates up to 192 kHz. Place the converter between a digital audio processor and a left/right analog power amplifier, then use the SPI interface to configure supported operating functions. Its 3.3 V to 5 V supply range simplifies interoperability with common digital source equipment, while the 192 kHz capability preserves high-resolution source rates. The key design tradeoff is the need for clean analog routing and appropriate output filtering, since converter performance alone cannot correct noise introduced by an unstable reference or poorly implemented output stage.
추천
CD and DVD Player
The WM8716SEDS/V is appropriate for a CD or DVD player that requires a dedicated stereo digital-to-analog conversion stage. Its two-channel architecture maps directly to left and right playback, while 24-bit resolution and support for rates up to 192 kHz provide headroom for higher-rate source formats. The SPI-compatible control path allows a system controller to configure supported DAC behavior without requiring a parallel data interface. The implementation must maintain a clean separation between digital control traces and the analog output region, and it must supply the interface format and clocking expected by the converter before reliable playback can be confirmed.

Set-Top-Box Audio Output
A set-top box can use the WM8716SEDS/V to convert decoded digital television audio into a stereo analog output for downstream amplification. The device supports 24-bit conversion at rates up to 192 kHz and uses a compact 28-SSOP package, making it suitable for space-conscious consumer electronics. Its SPI control interface simplifies integration with the box's main processor, while the 3.3 V to 5 V operating range supports common system rails. Board designers should reserve uninterrupted analog output routing, provide local supply decoupling, and verify the required master-clock and data framing settings for the selected television-audio standard.
추천
Digital Television Audio
The WM8716SEDS/V supports digital-TV audio designs requiring a two-channel high-resolution stereo DAC. Its maximum 192 kHz sampling rate accommodates high-rate decoded audio, and the 24-bit conversion format avoids limiting the digital word length unnecessarily. The SPI-compatible serial control interface gives the television main processor a compact method for configuring supported operating modes. Because analog signal integrity can affect perceived audio quality, the converter should be placed near the output connector or amplifier input, while digital clock and data routing should remain separated from the stereo output traces.
추천
High-Resolution Audio Source
The WM8716SEDS/V is suitable for a high-resolution audio source that must preserve the source rate through digital-to-analog conversion. The converter supports stereo operation, 24-bit data, and sampling rates up to 192 kHz, allowing a 44.1 kHz, 48 kHz, or higher-rate digital stream to be handled without forcing the product into a lower-rate class. The system designer must still align the input data width, sample rate, clocking, and de-emphasis requirements with the digital source. Analog output filtering and the next amplification stage determine how much of the converter's dynamic performance reaches the listener.
추천
Multimedia Audio System
The WM8716SEDS/V can serve as the stereo playback converter in a multimedia system combining stored digital content, television audio, and local high-resolution sources. A processor can use the SPI interface to manage supported configuration functions while the converter maintains a consistent two-channel output format. The 3.3 V to 5 V supply range supports integration with mixed-voltage logic, although separate analog and digital decoupling paths remain necessary. Compared with a discrete multi-resistor DAC implementation, the integrated converter reduces assembly complexity and provides a defined control interface, although it still requires careful analog grounding and output routing.

설계 노트
Separate the stereo analog outputs from SPI data, SPI clock, and other fast digital routes to minimize crosstalk into the audio path. Use the pin-description table in the Cirrus Logic datasheet when assigning tracks, and route each analog output through its intended output-filter network without sharing narrow digital-adjacent paths. Keep the converter close to the analog output connector or next amplifier stage when practical.
Place the required analog and digital decoupling capacitors directly beside their associated supply pins, using short ground returns. Keep switching-regulator currents and magnetic components away from the converter's analog inputs and stereo outputs. Check both 3.3 V and 5 V operating conditions against the complete analog and digital performance requirements before finalizing the power architecture.
Do not assume that identical SSOP pin assignments guarantee correct operation without checking clock mode, data framing, reset behavior, and control-register defaults. Compare the complete connection and register information in the applicable manufacturer documents, and preserve the exact ordering code in the production BOM. Treat the WM8716SEDS/RV as a drop-in candidate only after confirming its documentation and supply status.
The WM8716SEDS/V accepts digital audio and clock signals, so source timing margin must be established before evaluating analog output quality. Use the pin-description table in the manufacturer datasheet to identify clock and data pins, keep the interface routing away from analog outputs, and verify startup, mute, and configuration sequencing in software. A clean digital interface is a prerequisite for reliable stereo playback.
