WM8533ECSN/R - 24-Bit 192kHz Stereo DAC | Cirrus Logic
N.º da peça: WM8533ECSN/R ✓ AtivoWM8533ECSN/R Visão geral
An audio DAC is a data converter that transforms digital audio samples into analog voltage signals. Within the broader hierarchy of ADC/DAC converters, data converters, and integrated circuits, a stereo DAC supports two independent analog output channels. The WM8533ECSN/R operates at up to 192kHz and accepts 24-bit audio data, making its digital audio interface suitable for high-resolution consumer and embedded audio systems.
Key verified features include 24-bit resolution, a maximum sample rate of 192kHz, stereo operation, 2Vrms ground-referenced line outputs, and configurable I2C or SPI control. The compact 20-WCSP package is intended for space-constrained designs where a conventional leaded package or larger multi-pin surface-mount package would be inconvenient. Exact device dimensions, pin assignments, clock requirements, supply voltages, and output topology details require confirmation from the manufacturer datasheet.
The converter can sit at the output of a digital audio pipeline, receiving serial audio data from a USB interface, audio processor, Bluetooth receiver, or digital transport. I2C is useful for compact control buses, while SPI provides an alternative digital control path. The verified 2Vrms ground-referenced output description indicates that the analog stage is intended for line-level audio rather than direct headphone drive.
Typical uses include premium portable audio products, digital media equipment, active speakers, audio docking systems, and embedded playback platforms. In each case, the 24-bit and 192kHz capabilities allow high-resolution source material to be represented, although actual signal fidelity also depends on clocking, analog layout, power quality, output filtering, and the surrounding signal chain.
Designers should verify the complete pinout and reference circuit directly against the manufacturer datasheet before PCB layout. The 1.84 mm by 1.77 mm WCSP requires fine-pitch assembly, and the I2C and SPI interface pins, analog outputs, supplies, and ground connections must be routed according to the documented reference layout.
This page consolidates verified distributor descriptions, package information, interface details, and selection guidance while clearly identifying parameters that still require datasheet verification. It also records that no verified pin-to-pin replacement candidates were found, avoiding unsupported substitution claims.

Aplicações típicas
WM8533ECSN/R é adequado para 6 aplicaçãos: High-Resolution Portable Audio, Digital Media Player, Network Audio Receiver, Bluetooth Audio Speaker, Active Speaker and Soundbar, Digital Audio Interface Product.
High-Resolution Portable Audio
The WM8533ECSN/R fits compact portable-audio designs that decode 24-bit PCM material at rates up to 192kHz. Its 20-WCSP package occupies only a 1.84 mm by 1.77 mm footprint according to verified distributor data, helping preserve board area for storage, controls, and radio or interface circuitry. The converter can sit after a digital audio decoder, with I2C or SPI used for configuration. The verified 2Vrms ground-referenced output should feed the product's line-level or headphone-amplifier stage. Because this is a bare DAC rather than a confirmed integrated headphone driver, output-current, impedance, noise, and distortion limits must be checked in the datasheet before the analog load is finalized.
Recomendado
Digital Media Player
A digital media player can use the WM8533ECSN/R as the final 24-bit stereo conversion stage when supporting high-resolution playback up to 192kHz. The I2C or SPI control options allow configuration from a media processor, while the compact 20-WCSP package supports dense consumer-electronics layouts. Its verified 2Vrms ground-referenced line output is appropriate for a line-level analog section or external amplifier input. The implementation must preserve the converter's documented digital timing and grounding scheme, particularly if the source content can switch between standard- and high-resolution rates, because unsupported clock configurations cannot be resolved from the supplied distributor excerpts.
Recomendado
Network Audio Receiver
The WM8533ECSN/R is suitable for a compact network-audio receiver or streamer that accepts digital audio from a network interface and requires a 24-bit, 192kHz stereo analog output. I2C can provide a low-pin-count control connection to a network or system controller, while SPI is available if the host architecture benefits from that interface style. The converter's 2Vrms ground-referenced output can feed an analog volume-control and amplifier chain. Its small 1.84 mm by 1.77 mm WCSP helps minimize board area, but successful implementation depends on exact clock support, supply rails, reference layout, and de-emphasis or filtering requirements documented in the manufacturer datasheet.
Recomendado
Bluetooth Audio Speaker
A Bluetooth speaker architecture can place the WM8533ECSN/R after a digital Bluetooth audio receiver to regenerate 24-bit stereo content at rates up to 192kHz where the upstream link supports it. The converter's verified I2C and SPI control interfaces make it adaptable to different host processors, and the 20-WCSP package leaves more PCB area for the radio, power amplifier, and thermal management. The 2Vrms ground-referenced output should feed a line-level amplifier stage rather than being assumed to drive a speaker directly. Real products must also account for the DAC's exact clocking, analog filtering, ground reference, and output-impedance requirements before selecting the downstream speaker amplifier.
Recomendado
Active Speaker and Soundbar
The WM8533ECSN/R can provide the stereo line-level conversion stage in an active speaker, soundbar, or compact stereo system. Its verified 24-bit and 192kHz processing capability supports high-resolution digital sources, while the small 1.84 mm by 1.77 mm WCSP is useful where the main board must also contain power amplification, connectors, and controls. The I2C or SPI programming path can be linked to the system's main controller for channel and configuration management. The 2Vrms ground-referenced output is suited to an intermediate analog gain stage; designers should verify documented output impedance, noise, distortion, and clock modes before connecting an amplifier whose input and gain assumptions differ.
Recomendado
Digital Audio Interface Product
The WM8533ECSN/R is appropriate for a digital-to-analog audio accessory where a source controller sends digital audio over I2C or SPI-compatible control and data paths and users require a line-level stereo output. Its verified support for 24-bit data and rates up to 192kHz makes it relevant to high-resolution playback equipment, while its 20-WCSP construction supports compact enclosures. A practical implementation should provide clean analog and digital supply rails, follow the manufacturer's recommended decoupling and output filtering, and preserve the supported master-clock relationship between the host and DAC. Exact supported data formats and clock modes must be confirmed because they are not present in the supplied verified excerpts.

Notas de projeto
Use the manufacturer reference layout and pin table before placing the 1.84 mm by 1.77 mm 20-WCSP. The verified excerpts do not identify individual pin functions, so assigning analog outputs, digital inputs, supplies, or grounds from general knowledge would risk creating an invalid board. Preserve the documented ball assignments, escape geometry, and exposed-contact requirements exactly, then confirm the assembly process and inspection coverage with the packaging documentation.
Route the I2C or SPI interface as a compact, controlled digital group and verify the supported clock and data formats from the datasheet. The part supports 24-bit conversion at rates up to 192kHz, but those headline specifications do not identify every legal interface mode. Pay particular attention to source, destination, and ground-return paths near the WCSP, and avoid routing the digital bus across or beneath sensitive analog-output and filtering regions.
Do not treat the verified 2Vrms ground-referenced output description as proof that the WM8533ECSN/R can directly drive headphones or speakers. Confirm output impedance, current capability, DC operating point, recommended filtering, and supported loads from the manufacturer datasheet. If the required load is beyond the documented capability, add an appropriate line-level or headphone amplifier and account for its gain, noise, headroom, and power-supply requirements.
Informações de conformidade
The supplied verified data does not extract RoHS, REACH, lead-free, halogen-free, or conflict-minerals declarations. AEC-Q100 is not applicable to this consumer audio DAC because no automotive qualification is stated.
