WM8759GED/V - 24-Bit 192kHz Stereo DAC | Wolfson
料号： WM8759GED/V ✓ 量产中WM8759GED/V 概述
A stereo DAC is an audio signal-chain component that converts digital PCM audio samples into analog left and right channel voltages. It belongs to the broader digital-to-analog converter and audio interface hierarchy. An integrated headphone buffer further conditions those analog signals for headphone loads, allowing the WM8759GED/V to serve both fixed-line and variable-headphone outputs within portable consumer-audio designs.
The verified manufacturer-datasheet description identifies the principal audio capabilities as 24-bit resolution, operation up to 192kHz, stereo conversion, an integrated headphone driver, line output, and headphone output. These specifications make the device relevant to digital media players and other systems that reproduce CD-quality or higher-resolution digital audio and require both line-level and headphone connections.
The WM8759GED/V's architecture combines a stereo DAC section with a headphone-output stage rather than treating headphone drive as a completely separate function. Integrating those blocks can simplify system partitioning and reduce board area. The precise digital interface format, analog performance figures, clocking requirements, output topology, and supported sample-rate details require confirmation from the complete manufacturer datasheet and must not be inferred from the available distributor summary.
Typical uses include portable DVD players, MP3 players, and consumer equipment featuring line and headphone outputs. Its 24-bit, 192kHz capability supports high-resolution digital-audio paths, while the integrated headphone buffer is especially useful where a product needs both an external line connection and a direct headphone connection without adding another discrete output buffer.
Designers should verify the exact 32-lead QFN footprint, exposed-pad requirements, decoupling, analog routing, and digital interface timing before layout release. Headphone and line outputs should also be checked for load compatibility, startup behavior, and channel alignment. Because the verified web results provide only a functional summary, unavailable electrical, environmental, and package details are marked separately rather than estimated.
This page consolidates the verified WM8759GED/V function, distributor availability information, qualified same-family references, and practical selection guidance. It distinguishes documented capabilities from parameters that still require confirmation, helping engineers locate the datasheet, assess replacement risk, and plan a portable-audio design without presenting unverified specifications as facts.

典型应用
WM8759GED/V 适用于 6 应用s: Portable MP3 Player, Portable DVD Player, Consumer Line-Output Equipment, High-Resolution Digital Audio Source, Headphone Amplification, Digital Audio Interface Card.
Portable MP3 Player
The WM8759GED/V fits a portable MP3 player because it combines a 24-bit, 192kHz stereo DAC with an integrated headphone buffer in one device. According to the manufacturer-datasheet description, the converter supports both line and headphone outputs, making it suitable for a compact playback path that must connect to external audio equipment as well as headphones. Using the integrated buffer can reduce the number of separate output stages, although the designer must verify clocking, supply voltages, output loading, and thermal limits from the complete datasheet before finalizing the PCB.
推荐
Portable DVD Player
The WM8759GED/V is explicitly identified for portable DVD applications in the verified manufacturer-datasheet summary. Its 24-bit, 192kHz stereo DAC converts digital soundtrack data into analog line-level signals, while the integrated headphone buffer provides a second output path for personal listening. This combination suits a compact portable design with wired headphones or an external line connection. Layout must keep analog and digital return paths controlled, follow the required component placement, and account for the 32-lead QFN footprint and exposed-pad requirements.
推荐
Consumer Line-Output Equipment
The WM8759GED/V is suitable for consumer equipment that needs both line output and headphone output from one stereo DAC. According to the verified datasheet description, the device performs 24-bit digital-to-analog conversion at rates up to 192kHz and includes an integrated headphone buffer. That arrangement can simplify a product with a fixed analog line connection and a user-facing headphone jack. Before implementation, confirm output impedance, headphone-load limits, startup behavior, channel alignment, and analog filtering requirements using the complete manufacturer documentation.
推荐
High-Resolution Digital Audio Source
A high-resolution digital-audio source can use the WM8759GED/V as the final 24-bit, 192kHz stereo conversion stage. According to the verified manufacturer-datasheet summary, the DAC supports line and headphone outputs for consumer playback equipment. The maximum 192kHz capability makes it relevant to sources that store audio above conventional CD rates, provided the upstream interface, clocking, and system path support that rate. Engineers should confirm the required serial format, master-clock range, and supported sample-rate combinations before selecting it as the output converter.
推荐
Headphone Amplification
The integrated headphone buffer makes the WM8759GED/V applicable to headphone-output stages in portable consumer-audio products. According to the verified datasheet description, the same 24-bit, 192kHz stereo DAC feeds both headphone and line outputs, avoiding a separate converter for each destination. The practical benefit is reduced board partitioning and component count. Headphone capability must still be validated against the target impedance and output-power expectations, and the analog output network, grounding, and supply filtering should follow the manufacturer's reference layout.
推荐
Digital Audio Interface Card
The WM8759GED/V can serve as the analog-output stage of a digital-audio interface card that accepts digital audio and offers selectable line or headphone connections. According to the verified manufacturer-datasheet description, it provides a 24-bit, 192kHz stereo DAC with both output types integrated. This arrangement is useful in equipment where a host transfers digital audio to a dedicated playback module. The design must isolate converter clocks from noisy digital activity, implement supported digital formats correctly, and verify line-output amplitude and headphone-load behavior from the full datasheet.

设计说明
Confirm the complete 32-lead QFN land pattern, exposed-pad connection, solder-mask clearance, and paste stencil before layout release. The supplied excerpts identify the WM8759GED/V as a 32-lead QFN family device but do not reproduce the dimension drawing. Use the manufacturer package drawing rather than copying a generic QFN footprint, and verify pin 1 orientation because the exposed pad may have a specified electrical connection.
Separate digital interface routing from the DAC analog outputs and headphone buffer, while maintaining a continuous return path beneath the device where the reference layout requires it. Place required input, output, and supply decoupling components at the pins identified in the manufacturer datasheet. Because the verified summary omits the reference schematic and internal block diagram, component values and placement should not be inferred from generic Wolfson designs.
Treat the digital interface and clock signals as high-speed communication paths even though the part is categorized as an audio converter. Confirm the supported audio format, master-clock frequency, bit-clock polarity, and framing from the complete datasheet. Route clock and data away from headphone and line outputs, use a continuous ground reference, and avoid adding termination or filtering unless the manufacturer interface specification supports it.
Do not assume that the related WM8759GED and WM8759GED/RV order codes are unconditional drop-in replacements. The verified excerpts do not quantify differences in temperature grade, qualification, marking, electrical limits, or packaging. Before substitution, obtain the manufacturer order-code information and compare those attributes, the digital interface, clocking, analog performance, and exposed-pad requirements.
Use separate analog and digital supply sections only as directed by the manufacturer datasheet, and preserve the stated sequencing relationships if power rails are independently controlled. The supplied data does not provide supply-voltage limits or startup timing, so do not infer them from related codecs. Validate headroom, quiescent-current demand, and analog-output settling at the maximum intended clock and sample rate.
合规信息
The verified excerpts do not provide formal RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations. Compliance must be confirmed using the manufacturer product documentation or a supplier declaration.
