WM8725CGED 개요
The WM8725 belongs to the audio DAC hierarchy: digital-to-analog converter, audio converter, data-acquisition and signal-conversion integrated circuit. Its function is to convert digital audio samples into left and right analog output signals while preserving low-noise performance for portable audio equipment, video CD players, and related consumer audio systems. The selectable serial interface supports 16-bit to 24-bit digital input formats, while integrated digital filtering helps shape the conversion output.
Key verified features include stereo DAC operation, 24-bit resolution, 96 kHz operation, normal or I2S-compatible serial data interfaces, and 99 dB signal-to-noise performance. The 14-SOIC package is appropriate for conventional surface-mount PCB assembly. Exact supply-voltage limits, analog output specifications, clock requirements, filter characteristics, and electrical operating limits were not included in the supplied source text and are therefore not inferred here.
The device architecture combines a digital input interface, digital filtering, and sigma-delta DAC stages. This arrangement is suitable when a system accepts digital audio from a decoder, portable player, or digital audio processor and requires analog stereo outputs. The 99 dB SNR figure provides a concrete selection criterion when comparing audio-conversion stages, although system-level noise also depends on the supply, clock, analog output network, grounding, and downstream amplifier.
Typical applications include portable audio equipment, video CD players, digital audio adapters, compact stereo systems, and embedded audio products. In each case, the important design question is whether the required input word length, sample rate, interface mode, supply arrangement, and analog output topology match the device and its application circuit.
A key design consideration is to preserve clean analog and digital grounding while keeping the digital interface and clock signals away from sensitive analog output paths. Decoupling and output filtering should follow the manufacturer application guidance once the complete electrical data is available. This page synthesizes the verified distributor specifications, source links, and engineering context rather than adding unverified datasheet values.
The verified distributor records identify Cirrus Logic as the current source brand and describe WM8725CGED as a 24-bit, 96 kHz, stereo, 14-SOIC audio DAC. LCSC also reports the part as in stock with a listed price of $1.0043, while current quantity pricing beyond that single source is not provided.

일반적인 애플리케이션
WM8725CGED 적합 용도: 6 애플리케이션s: Portable Audio Equipment, Video CD Audio Output, Digital Audio Adapter, Compact Stereo Audio System, Digital Audio Interface Module, Stereo Audio Signal-Chain Prototype.
Portable Audio Equipment
The WM8725CGED fits portable audio products because the verified data identifies portable audio equipment as a target application. Its 24-bit stereo DAC supports digital inputs from 16 bit to 24 bit, while normal or I2S-compatible serial interfaces provide flexibility for a digital audio source. The 99 dB SNR specification gives a concrete performance baseline for a compact audio path. Designers should still verify supply voltage, power consumption, clocking, and analog output requirements before selecting it for battery-powered equipment.
추천
Video CD Audio Output
WM8725CGED is explicitly described for video CD players and similar portable-audio applications. The stereo DAC can accept digital audio data through selectable normal or I2S-compatible interfaces, making it suitable for systems where a decoder supplies serial audio samples. Its verified 24-bit resolution and 99 dB SNR are useful criteria for maintaining clean reconstructed audio. Final design work must include the exact clocking scheme, required digital format, analog output filter, and board-level grounding.
추천
Digital Audio Adapter
A digital audio adapter can use WM8725CGED when it needs to translate a digital audio stream into left and right analog outputs. The device’s verified 24-bit input support, 96 kHz maximum stated operation, and selectable serial interface provide a practical conversion core for compact adapters. The application should be designed around the exact digital timing and analog output topology from the full datasheet. Power, ground separation, and output filtering strongly influence real-world audio performance.
추천
Compact Stereo Audio System
WM8725CGED can serve as the stereo conversion stage in a compact audio system that receives digital samples and drives analog audio circuitry. Its 24-bit architecture and 99 dB SNR specification provide a measurable starting point for signal-quality evaluation. Because the verified data does not state the exact supply voltage, output impedance, distortion, or temperature range, those parameters must be checked before amplifier and speaker selection. Keep digital and analog return paths controlled to avoid degrading the reconstructed signal.
추천
Digital Audio Interface Module
The WM8725CGED is appropriate for a module that accepts digital audio from a host processor or decoder and produces analog stereo outputs. Its selectable normal or I2S-compatible serial interface reduces the need for a separate format-conversion stage, provided the host timing matches the device requirements. The 14-SOIC package supports conventional surface-mount assembly. Validate signal levels, clock ratios, startup behavior, and analog output loading using the complete manufacturer documentation before releasing the module.
추천
Stereo Audio Signal-Chain Prototype
For prototypes and evaluation boards, WM8725CGED provides a focused stereo DAC function with verified 24-bit resolution, 96 kHz stated operation, and 99 dB SNR. It is useful for testing digital-to-analog reconstruction before committing to a production audio path. The prototype should expose the required digital interface, supply rails, analog outputs, and ground reference clearly. Do not infer pin functions or electrical limits from the package alone; cross-check the exact WM8725CGED datasheet and compare output behavior with the target amplifier.

설계 노트
Keep the digital serial interface and clock routing physically separated from the analog output path. The verified WM8725CGED description confirms a digital-audio DAC with selectable normal or I2S-compatible input, but it does not provide a complete layout drawing. Use the manufacturer datasheet to confirm pin locations, then preserve a quiet analog return and minimize digital current paths near the output network.
Decoupling and supply design must be based on the complete WM8725 electrical limits and the application clocking scheme, which are not included in the supplied source snippets. Do not infer supply voltage or capacitor values from the 24-bit or 96 kHz specifications. Confirm the analog and digital supply arrangement, allowable startup sequence, and output-load requirements in the manufacturer datasheet before laying out the board.
A 14-SOIC package is not sufficient evidence of drop-in compatibility. Confirm the actual pinout, analog output implementation, clock polarity, digital word length, and interface timing for each candidate. The supplied cross-reference data identifies only an unspecified Burr-Brown pin-to-pin candidate, so any replacement must be approved through a complete electrical and pin-level review rather than package-name matching alone.
규정 준수 정보
The supplied distributor and manufacturer-linked search results identify the component and audio specifications but do not provide RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations.
