WM8783GED/V Stereo 98kHz Audio ADC | Cirrus Logic
MPN： WM8783GED/V ✗ 停產WM8783GED/V 概覽
An ADC is an analog-to-digital converter, a mixed-signal integrated circuit that converts continuously varying analog audio voltages into digital samples. In the broader component hierarchy, an audio ADC belongs to data converters, mixed-signal semiconductors, and signal-chain ICs. The WM8783GED/V therefore sits between an analog microphone or line input and a digital audio interface such as I2S.
The principal verified features are stereo operation, a 24-bit conversion format, I2S digital output, and a family sampling-rate capability reported as 98 kHz in distributor material and 96 kHz in the Wolfson-family result. The device is identified as low power, making it relevant to embedded audio systems where power consumption, channel count, and board area constrain the architecture. The manufacturer-family datasheet source also indicates that the device is manufactured on a CMOS process and is ESD-sensitive.
WM8783GED/V is suitable for digital recording front ends, USB audio adapters, industrial audio capture, portable audio equipment, and consumer audio systems. In each case, the stereo ADC can convert left and right analog inputs into digital samples for downstream processing or transmission. The I2S interface helps simplify connection to digital audio controllers, DSPs, and microcontrollers, although the host device must support the required clocking and framing format.
When selecting this part, verify the exact electrical characteristics, analog input range, clock requirements, master or slave operating mode, and package pin assignment in the current manufacturer documentation. Do not infer those values from generic ADC descriptions. For replacement work, confirm that the candidate uses the same SOIC footprint and pin-to-pin signal arrangement rather than relying only on a similar sample rate or converter function.
This page combines the verified source snippets for the WM8783GED/V family with engineering-oriented application and selection context. Because the retrieved data does not provide a complete current manufacturer product page, several detailed parameters remain explicitly marked for verification rather than being guessed.

典型應用
WM8783GED/V 適用於 6 應用s: Stereo Audio Capture, USB Audio Adapter, Industrial Audio Monitoring, Portable Audio Equipment, Digital Recording Front End, Consumer Audio System.
Stereo Audio Capture
WM8783GED/V fits a stereo capture front end because the verified family description identifies it as a stereo audio ADC with 24-bit I2S output. The ADC can digitize left and right analog audio channels for storage, monitoring, or transmission while leaving digital processing to a host controller. The reported 98 kHz sampling capability is relevant to audio systems operating near CD-rate conversion, although the exact /V sample-rate limit and analog input range must be confirmed in the current datasheet.
推薦
USB Audio Adapter
The WM8783GED/V can serve as the analog-to-digital conversion stage in a USB audio adapter when the host supports the required I2S clocking and data framing. Its verified 24-bit stereo identity supports a conventional digital-audio signal path from analog input circuitry to a USB audio controller such as the listed ATMEGA32U4-MU family part. Board-level attention is still required for input coupling, ground separation, ESD protection, and ensuring that the selected /V suffix supports the intended sample rate.
推薦
Industrial Audio Monitoring
For industrial audio monitoring, WM8783GED/V provides a compact stereo conversion function for microphones, line-level inputs, or conditioned sensor outputs. The verified low-power positioning is useful when the system must digitize two channels without adopting a larger codec. Because the retrieved data does not state the analog input range, SNR, THD, or operating temperature, the analog front end should be designed only after those parameters are verified from the manufacturer-family datasheet.
推薦
Portable Audio Equipment
WM8783GED/V is relevant to portable and embedded audio equipment because the verified product description emphasizes low power and stereo operation. A battery-powered product can use the ADC to capture audio before passing I2S data to a low-power digital controller, provided the host supports the required clocking. The package and exact power consumption are not fully present in the retrieved snippets, so battery-life calculations and thermal design must wait for verified operating-current and supply-voltage data.
推薦
Digital Recording Front End
The WM8783GED/V can form the conversion stage in a digital recording front end where two analog channels must become digital audio samples for a DSP or memory subsystem. Its verified 24-bit stereo format and I2S output align with common digital-recording architectures, while the SOIC-8 package supports compact board placement. Designers must still confirm clock polarity, data timing, channel alignment, input scaling, and whether the exact part is qualified for the product’s operating environment.
推薦
Consumer Audio System
WM8783GED/V is suitable for a compact consumer audio conversion block where analog stereo sources need to reach a digital audio processor or controller. The verified WM8783 family description provides the key semantic match—stereo, low power, 24-bit, I2S ADC—without requiring a complete audio codec. This makes it useful in systems that already provide their own microphone amplifier, volume control, and output stage. Verify sample-rate and electrical limits before selecting it against newer codec families.

主要差異化特點
- Stereo audio ADC positioning (對比CS4231)
- Digital interface alignment (對比WM8783GED/RV)
- Legacy-family sourcing visibility (對比WM890)
設計說明
Place the analog input and digital interface paths according to the current WM8783 datasheet layout guidance. Keep microphone or line-input traces away from I2S clock and data traces, maintain a continuous ground reference, and place decoupling capacitors close to the device pins. Because the retrieved data does not include the complete pinout or recommended capacitor values, do not copy generic ADC layouts without checking the exact manufacturer drawing.
I2S signals are timing-sensitive even when the data rate is moderate. Route clock, data, and channel-selection connections with controlled length and impedance, and keep the digital return path close to the converter. Confirm whether the host provides or receives the master clock and validate setup and hold timing with an oscilloscope. The verified sources identify I2S output but do not provide the complete timing table.
Do not treat a similar converter function as proof of replacement compatibility. The cross-reference results mention CS4231 and WM890, but the supplied data does not verify their package dimensions, pin mapping, clock mode, supply voltage, or electrical limits. For WM8783GED/RV, verify the meaning of the /RV suffix against the current datasheet before substituting it for the /V ordering code.
The verified data identifies the WM8783 as low power but does not provide the supply voltage, active current, standby current, or power-consumption limits. Before estimating battery life or sizing a regulator, retrieve those parameters from the manufacturer-family datasheet. Use the actual worst-case load and conversion mode in the design; do not estimate from the generic phrase low power.
The source material identifies the device as ESD-sensitive. Apply the manufacturer’s handling and board-assembly recommendations, use appropriate protection at exposed analog inputs, and inspect the production process for uncontrolled electrostatic events. ESD protection does not replace correct grounding, input filtering, or compliance with the exact absolute-maximum ratings in the full datasheet.
合規資訊
The verified data identifies the device as ESD-sensitive and manufactured on a CMOS process, but it does not provide compliance declarations for RoHS, REACH, lead-free status, halogen-free status, or conflict minerals.
