WM8726CGED - 24-Bit 192 kHz Stereo DAC | Cirrus Logic
Teilenummer: WM8726CGED ✓ AktivWM8726CGED Übersicht
A stereo DAC is an audio data-converter IC that transforms digital PCM samples into left- and right-channel analog voltage signals. It belongs to the ADC/DAC hierarchy within integrated circuits and ultimately falls under semiconductor signal-conversion and audio-processing devices. In an audio signal chain, the WM8726CGED typically follows a digital audio processor and precedes an analog output amplifier, volume-control stage, or speaker-driving circuit.
The verified 24-bit resolution supports high-fidelity digital audio reproduction, while operation up to 192 kHz accommodates high-sample-rate source material. The pin-selectable interface provides compatibility with I2S, 16-bit right-justified, and DSP formatting, reducing host-format adaptation requirements. Its 3.0 V to 5.5 V supply operation supports both common low-voltage digital and mixed analog-supply system architectures.
The WM8726CGED provides separate left- and right-channel outputs, digital audio inputs, clock inputs, mute control, and digital control signaling. Its architecture is intended for stereo playback systems where a conventional audio DAC is required without the complexity of a general-purpose conversion subsystem. The package also reflects its role as a compact, surface-mount audio converter for volume-production consumer and automotive electronics.
Typical applications include DVD players, home-theater systems, digital televisions, set-top boxes, and automotive audio equipment. In these systems, the device can accept digital audio from a decoder or processor, generate left and right analog outputs, and provide digital mute control. System-level performance still depends on the external clock scheme, output filtering, power-supply implementation, analog gain stage, and speaker or headphone amplifier.
Designers should follow the manufacturer’s recommended application circuit, interface timing, decoupling, and output-filtering guidance. Clock routing requires particular care because audio data must be synchronized with the appropriate bit clock and left/right channel signal. Adequate analog and digital supply decoupling helps isolate the converter from switching noise and prevents unintended coupling into the analog output path.
This page consolidates verified distributor identification, package and interface facts, supply information, a pin-compatible WM8725 option, application guidance, and engineering-oriented selection notes. It distinguishes documented replaceability from broader functional similarities so designers can avoid treating devices with the same general specifications as guaranteed drop-in replacements.

Typische Anwendungen
WM8726CGED ist geeignet für 6 Anwendungs: DVD Player Stereo Audio, Home-Theater System, Digital Television Audio, Digital Set-Top Box, Automotive Audio Head Unit, Portable Digital Audio Source.
DVD Player Stereo Audio
The WM8726CGED fits a DVD-player output stage because it provides a 24-bit stereo DAC with operation up to 192 kHz and selectable I2S, right-justified, or DSP input formats. It can receive decoded digital audio and produce separate VOUTL and VOUTR signals for the following analog volume and amplifier stages. The 3.0 V to 5.5 V operating range supports low-voltage consumer designs, while the 14-lead SOIC package simplifies compact board construction. Final audio performance still depends on the external reconstruction filter, analog gain stage, clock source, and power-supply decoupling.
Empfohlen
Home-Theater System
The WM8726CGED is suitable for the stereo playback path of a home-theater system because its 24-bit conversion and 192 kHz maximum sample rate accommodate high-resolution source formats. The selectable digital interface allows the system architect to connect an audio decoder using I2S, 16-bit right-justified, or DSP signaling. Separate left and right outputs support conventional stereo volume-control and amplifier stages. Because this is a stereo DAC rather than a multichannel processor, surround-channel routing must occur upstream, while clocking and output filtering require careful PCB implementation.
Empfohlen
Digital Television Audio
The WM8726CGED can serve as the stereo DAC in a digital television when the television accepts digital audio in one of its supported formats. Its 24-bit resolution, 192 kHz capability, and selectable I2S, right-justified, or DSP interface make it adaptable to decoder and audio-processor outputs. The 3.0 V to 5.5 V supply range supports compact consumer-electronics power architecture, while the 14-lead SOIC package remains compatible with surface-mount assembly. TV designers must still account for HDMI-related clocking, source synchronization, mute behavior, and the analog speaker-amplifier path.
Empfohlen
Digital Set-Top Box
The WM8726CGED is appropriate for a digital set-top box that needs a dedicated stereo digital-to-analog output stage. The device accepts common serial audio formats through its pin-selectable interface and converts digital samples into separate left and right analog outputs at rates up to 192 kHz. Its 24-bit processing and low-voltage 3.0 V to 5.5 V operation align with processor-based consumer systems. In a practical design, the digital source must provide the correct bit clock and channel clock, and the analog output must feed a suitable low-pass, volume-control, and line or headphone-amplifier network.
Empfohlen
Automotive Audio Head Unit
The WM8726CGED is identified by the manufacturer documentation as suitable for automotive audio systems, making it applicable to a stereo head-unit or auxiliary audio path. Its 24-bit, 192 kHz stereo conversion and selectable I2S, right-justified, or DSP input support modern vehicle infotainment audio architectures. The 3.0 V to 5.5 V supply range and 14-lead SOIC package suit compact electronics. Automotive qualification status is not confirmed by the supplied excerpts, so production use requires a current manufacturer declaration and the applicable environmental and quality requirements.
Empfohlen
Portable Digital Audio Source
The WM8726CGED can be used in a compact digital-audio source that converts stored or streamed PCM data into analog stereo outputs. Although the verified operating range of 3.0 V to 5.5 V is not a battery-specific specification, it permits low-voltage system designs using appropriately regulated rails. The 24-bit resolution, 192 kHz capability, and selectable audio interface support modern playback engines. Designers should minimize analog trace noise, provide stable clocking and filtering, and confirm that the device’s current draw and thermal behavior suit the target enclosure before portable qualification.

Wichtigste Unterscheidungsmerkmale

- Selectable digital audio formats (vs. WM8725CGED)
- Documented compatibility path for existing designs (vs. WM8725CGED)
Designhinweise
Keep the audio data, bit-clock, and channel-clock traces short and route them away from analog outputs and switching regulators. The supplied excerpts identify the interface as pin-selectable, so the mode configuration must match the host source exactly. Provide a continuous ground reference beneath the signal path, use a solid ground plane, and place decoupling capacitors close to their associated supply pins according to the manufacturer application circuit.
Treat clock routing as the highest-priority digital signal. Use the manufacturer’s timing diagrams to establish setup and hold requirements for BCKIN, the audio interface, and the left/right channel clock. Avoid long stubs, unnecessary vias, and parallel routing with switching-node traces. If the system clock is derived from an audio processor, verify frequency relationships and jitter tolerance before releasing the layout because nominal sampling-rate support alone does not guarantee robust synchronization.
Do not treat any stereo DAC with a 24-bit, 192 kHz headline specification as a drop-in replacement. The verified data explicitly documents WM8725 compatibility but does not establish equivalent performance for other devices. Before substituting a candidate, compare the complete pin list, supply pins, interface mode, clock requirements, mute polarity, analog output levels, filtering, and package dimensions. PCB artwork and schematic verification must both be completed before sourcing changes.
Compliance-Informationen
The supplied verified excerpts identify automotive applications but do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These fields remain unknown rather than being inferred.
