WM8783GED/RV - 24-Bit Stereo Audio ADC | Cirrus Logic
MPN： WM8783GED/RV ✗ 停產WM8783GED/RV 概覽
The WM8783 belongs to the audio ADC category within the broader analog-to-digital converter and mixed-signal IC hierarchy. Audio ADCs convert continuous analog audio signals into digital sample streams for processing, storage, transmission, or playback. The WM8783 is intended for applications such as set-top boxes, DVD systems, and other consumer audio equipment where stereo line-level signals must be digitized with a compact interface.
Key features include 24-bit resolution, a maximum sampling rate of 96 kSPS, stereo analog inputs, and an I2S output interface. The device is described as a compact, low-cost ADC for set-top box and DVD applications. Its stereo input architecture is suitable for two-channel audio acquisition, while the digital output allows direct connection to a digital audio processor, codec, or system interface.
The WM8783GED/RV is manufactured on a CMOS process and is therefore susceptible to electrostatic discharge damage during handling. ESD-safe handling procedures are important during soldering, inspection, and production assembly. The device's function is straightforward for an audio converter: analog signals enter through the stereo input pins, are sampled and quantized by the ADC, and are transferred over the I2S interface as digital audio data.
Typical applications include set-top box audio paths, DVD player analog input stages, consumer audio receivers, and embedded multimedia systems. The 96 kSPS maximum rate supports high-resolution audio conversion, while 24-bit data provides substantial dynamic range for line-level sources. System designers should verify the analog input range, reference implementation, clocking requirements, and digital interface configuration against the manufacturer datasheet before finalizing the circuit.
This page combines the WM8783GED/RV product identity, core ADC specifications, application guidance, and design considerations into a concise engineering reference. It is intended to help engineers identify suitable use cases, plan board-level integration, and evaluate equivalent parts without overlooking pin compatibility, interface requirements, or supply-availability constraints.

典型應用
WM8783GED/RV 適用於 6 應用s: Set-Top Box Audio Input, DVD Player Analog Audio Capture, Stereo Consumer Audio Receiver, Digital Audio Processor Feed, Multimedia Speaker Input, Audio Test and Measurement Front End.
Set-Top Box Audio Input
The WM8783GED/RV fits the analog audio input stage of a set-top box because it converts two single-ended 1 Vrms line-level signals into 24-bit stereo data at up to 96 kSPS. Place the converter close to the analog input connector and conditioning network, then route its I2S output to the system audio processor. The converter's compact 8-pin SOIC format reduces board area, while the high sampling rate supports broadcast and multimedia audio paths. Confirm clock generation, digital voltage compatibility, and grounding separation in the reference design.

DVD Player Analog Audio Capture
The WM8783GED/RV is appropriate for digitizing stereo line-level audio in a DVD player or similar consumer media system. Its 24-bit resolution and 96 kSPS maximum sampling rate provide useful operating margin for high-quality audio conversion, while the I2S output can feed a digital signal processor or audio codec. Use the manufacturer's recommended input conditioning and anti-alias filtering, and isolate the analog input path from switching-converter and digital-clock return currents.
推薦
Stereo Consumer Audio Receiver
For a stereo consumer audio receiver, the WM8783GED/RV can capture two line-level channels and provide 24-bit digital audio over I2S. The two-channel architecture matches conventional left and right program-audio inputs, and the 96 kSPS capability supports high-resolution source material. The practical benefit is a dedicated conversion stage that leaves the downstream processor responsible for decoding, volume control, and routing. Validate input headroom, sampling-clock jitter tolerance, and digital ground-return strategy before production release.
推薦
Digital Audio Processor Feed
The WM8783GED/RV can serve as the front-end converter ahead of a digital audio processor when the processor requires I2S stereo data. The device converts 1 Vrms single-ended inputs into 24-bit samples and supports operation up to 96 kSPS, which matches common multimedia processing rates. Keep the analog input section short, provide stable reference and clock connections, and verify that the processor's I2S word length, channel alignment, and clock-mastering assumptions match the converter configuration.
推薦
Multimedia Speaker Input
The WM8783GED/RV can digitize line-level stereo signals from a multimedia speaker amplifier or active speaker system before they enter a digital audio processor. The 24-bit conversion and 96 kSPS rate support high-resolution processing, while the small 8-pin SOIC package leaves PCB space for additional functions. Confirm the expected source impedance and signal amplitude at the input connector, then select external filtering and coupling components according to the manufacturer application guidance.
推薦
Audio Test and Measurement Front End
The WM8783GED/RV can serve as a compact stereo digitization front end in compact audio test equipment, provided the system meets the converter's input-range and performance requirements. A 24-bit, 96 kSPS ADC can capture two simultaneous analog channels and deliver the samples over I2S for analysis or storage. The designer should define anti-alias filtering, clock jitter, channel isolation, and calibration requirements before using the part in a measurement-grade product.

設計說明
Route the two analog input channels as short, symmetrical traces between the input network and the WM8783GED/RV. Keep switching-regulator outputs, high-current return paths, and digital clock lines away from the analog inputs. Use a continuous ground reference under the analog section and follow the manufacturer reference layout for component placement and decoupling.
The I2S data, bit clock, and frame-clock signals require controlled routing because timing errors can create channel misalignment or word-boundary errors. Avoid long parallel clock traces that can couple noise into data, provide a continuous return path, and confirm the relationship between the converter's clock requirements and the receiving audio processor before layout release.
Do not treat the WM8783GED/V ordering code as an automatic substitute for WM8783GED/RV. The ordering suffix may encode packing, temperature, or other commercial details, so verify the manufacturer ordering table, package marking, and change-control requirements. Also use the datasheet's ESD guidance because the device is manufactured on a CMOS process and classified as ESD sensitive.
合規資訊
The manufacturer datasheet identifies the WM8783 as an ESD-sensitive CMOS device. Specific RoHS, REACH, lead-free, halogen-free, and conflict-minerals declarations should be confirmed from current manufacturer documentation.
