WM8523GEDT Overview
An audio DAC is a data converter that transforms digital audio samples into proportional analog voltages or currents. In the signal chain, a digital-to-analog converter sits between an audio source and an analog line-output stage. Its resolution, sampling rate, interface, clocking, and output architecture determine how faithfully digital recordings can be reproduced.
The WM8523GEDT uses 24-bit resolution and supports sampling rates up to 192kHz. I2C and SPI interfaces provide flexible connection to an audio processor or digital transport. Its integral charge pump supports the internal generation of negative supply voltage, while the DC servo enables ground-referenced outputs without line-output coupling capacitors and helps reduce power-on pops and clicks.
Cirrus Logic describes the device as a stereo digital/analog converter with 2Vrms ground-referenced line-driver outputs. A single 3.3V supply rail simplifies system power planning. The output stage is intended for line-level audio paths, including consumer audio equipment, powered speakers, headphones through an external amplifier, and digital source components.
The device also includes software-controlled configuration and an integrated low-pass filter for removing out-of-band digital noise. System design should preserve clean analog and digital return paths, provide a stable low-noise 3.3V supply, and use the supported I2C or SPI interface correctly. Output loading, grounding, and external amplifier selection remain important system-level considerations.
This product data consolidates verified manufacturer and distributor information, interface characteristics, sourcing details, and practical design guidance. It is intended to help engineers evaluate the WM8523GEDT for compact, high-resolution stereo audio designs while clearly separating verified facts from parameters that require additional datasheet or design confirmation.

Typical Applications
WM8523GEDT is suitable for 6 applications: Powered Speaker Line Input, Network Audio Player, Digital Audio Source, CD and Streamer Front End, Headphone Amplifier Signal Chain, Multichannel Audio Front Panel.
Powered Speaker Line Input
The WM8523GEDT fits a powered-speaker input stage because it supplies two ground-referenced line outputs at up to 2Vrms from one nominal 3.3V rail. The 24-bit DAC can accept audio through I2C or SPI and operate at rates up to 192kHz, allowing a digital source to feed a suitable stereo amplifier. The integrated DC servo removes output coupling capacitors and helps reduce startup transients. The amplifier still needs the required voltage gain, current capability, output bandwidth, and stable reference.
Recommended
Network Audio Player
A network audio player can use the WM8523GEDT as the final digital-to-analog conversion stage after receiving PCM audio from a network or storage subsystem. I2C or SPI control supports configuration from a digital audio controller, while the two-channel 24-bit architecture preserves the source format without a separate converter per channel. The 2Vrms output and single-rail 3.3V architecture simplify integration into compact equipment with limited analog supply space.
Recommended
Digital Audio Source
The WM8523GEDT suits a digital source component that converts stored or received high-resolution PCM audio into a conventional analog line output. Its 24-bit resolution and 192kHz maximum rate support high-resolution playback, while I2C and SPI provide flexibility with the source controller. The integrated low-pass filter removes out-of-band digital noise, and the ground-referenced output removes line coupling capacitors, reducing assembly complexity in consumer audio products.
Recommended
CD and Streamer Front End
The WM8523GEDT can serve as the analog-output stage of a CD player, streamer, or compact music system that presents a stereo line-level signal to an amplifier or powered speaker. The 2Vrms ground-referenced outputs are suitable for conventional downstream audio stages, and the DC servo helps keep startup quiet without coupling capacitors. The design should still verify output loading, mute behavior, channel matching, and the required digital clock and format.
Recommended
Headphone Amplifier Signal Chain
The WM8523GEDT can provide a clean stereo line signal before an external headphone amplifier when the product architecture requires digital-to-analog conversion at line level. Its 24-bit resolution and up-to-192kHz operation help preserve high-resolution source data, while the single 3.3V supply simplifies rail planning around low-voltage digital systems. The headphone amplifier must provide the required gain and output current, and its input impedance should preserve the DAC's output performance.
Recommended
Multichannel Audio Front Panel
The WM8523GEDT can form one stereo conversion section within a multichannel audio product, such as a compact monitor controller or surround-signal front end. Two-channel, 24-bit conversion at up to 192kHz supports high-resolution multirate audio when the digital source and downstream amplifiers are compatible. The I2C or SPI interface reduces parallel data routing, while careful partitioning of analog and digital grounds is needed to prevent switching and amplifier currents from corrupting the line output.

Key Differentiators
- Single-supply, capacitor-free ground-referenced outputs (vs A conventional coupling-capacitor line-output implementation)
- High-resolution stereo conversion (vs Lower-resolution audio DAC implementations)
- Flexible digital control (vs Parallel-only or single-interface DAC configurations)
Design Notes
Power the WM8523GEDT from a stable, low-noise source within the verified 2.97V to 3.63V range, with 3.3V as the nominal system rail. Place the recommended decoupling network close to its supply and ground pins, and keep high-current amplifier and switching-converter paths out of the DAC return. Because the verified data confirms the voltage range but does not specify capacitor values or startup timing, use the current manufacturer datasheet and layout guidance for exact values.
Separate digital audio routing from the analog line-output path where practical. Keep the digital clock, I2C or SPI traces away from the ground-referenced outputs, use a continuous ground reference, and return amplifier currents directly to the appropriate supply structure. The WM8523GEDT's DC servo and integrated low-pass filter reduce external analog requirements, but they do not replace careful grounding, controlled impedance, and separation from noisy power stages.
Do not treat the WM8523GEDT as a speaker-power amplifier. Its verified 2Vrms outputs are line-level signals intended to drive a suitable downstream amplifier. Also verify the exact digital audio format, clock requirements, mute polarity, register initialization, and output loading against the current manufacturer documentation before layout release. The supplied search data confirms major features but does not provide the complete timing and register tables.
Compliance Information
The supplied verified data does not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These fields remain unknown rather than assumed.
