MPN: WM8350GEB/V ✓ פעילWM8350GEB/V סקירה
An audio codec is a mixed-signal semiconductor that converts digital audio samples into analog signals and analog sound signals into digital data. A stereo codec therefore normally handles left and right playback and recording paths. As an integrated circuit combining audio conversion with power management, the WM8350GEB/V belongs to the broader semiconductor and audio-interface hierarchy rather than being a simple analog amplifier or passive audio component.
The verified product information identifies the WM8350GEB/V as a 12-bit audio interface operating at 48 kHz. Its 129-BGA, 7 x 7 mm package is a principal selection constraint because pin-compatible alternatives must reproduce the same ball layout, exposed features, and board-level connectivity. The listed package also requires land-pattern and assembly inspection that cannot be completed from a distributor category listing alone. Detailed electrical limits, clock requirements, analog performance, power-rail values, and ball functions must be confirmed in the manufacturer datasheet before schematic or PCB release.
The integrated power-management function can simplify the architecture of portable and embedded audio products by placing conversion and rail support in one device. This integration may reduce the number of external supporting components when the application uses the complete WM8350 audio subsystem. The tradeoff is that its 129-ball package is less straightforward to hand-solder and more dependent on advanced assembly capability than a leaded or small-outline package. Designers should also validate startup sequencing, analog grounding, clocking, and codec-to-host interface timing against the intended system architecture.
Typical uses include portable media devices, smart displays, connected audio products, communication terminals, and embedded systems requiring stereo recording and playback. In these applications, the 48 kHz sampling rate supports conventional digital-audio workflows, while the 12-bit resolution defines the converter word length represented by the verified listing. System-level audio quality still depends on microphone conditioning, amplifier selection, clock jitter, analog layout, grounding, and power-supply implementation; the codec alone does not determine the final acoustic performance.
Before design-in, engineers should obtain the official WM8350 datasheet and verify the complete 129-ball pin map, recommended decoupling, supported clock modes, host interface, analog input and output limits, and absolute maximum ratings. The verified distributor record labels the part as an audio interface and 12-bit codec, but it does not provide those implementation details. PCB designers should use the manufacturer land pattern rather than deriving it from package dimensions, and assemblers should confirm whether the selected BGA assembly process supports the device's ball pitch and thermal requirements.
This page consolidates verified distributor identification, package constraints, cross-reference evidence, procurement questions, and application guidance that a basic catalog result does not provide. It also distinguishes verified facts from parameters requiring datasheet confirmation, helping engineers decide whether the WM8350GEB/V fits their PCB before committing to a 129-BGA design.

יישומים טיפוסיים
WM8350GEB/V מתאים עבור 6 יישוםs: Portable Media Player Audio, Smart Display Audio, Connected Audio Terminal, Stereo Recording Module, Industrial Control Panel Audio, Embedded Speech Interface.
Portable Media Player Audio
The WM8350GEB/V can serve as the stereo audio conversion and power-management centerpiece in a portable media player. Its verified 2-ADC, 2-DAC configuration supports separate left- and right-channel recording and playback paths, while the 12-bit converter resolution and 48 kHz sampling rate align with conventional consumer-audio workflows. Integrated power management may reduce support circuitry when the host design uses the manufacturer's reference architecture. However, the 129-BGA, 7 x 7 mm package requires a qualified assembly process. Before schematic approval, engineers must verify battery-rail compatibility, headphone or line-output limits, clock support, and the complete exposed-ball and thermal requirements in the manufacturer documentation.
מומלץ
Smart Display Audio
A smart display can use the WM8350GEB/V to consolidate stereo playback conversion and related power support into a compact interconnect area. The verified 12-bit resolution, 48 kHz sampling rate, and two DAC channels suit ordinary speech, music, and notification-audio paths. The 7 x 7 mm 129-BGA footprint can help reduce board area compared with separate converters and supporting regulators, although its 129 balls complicate routing and inspection. Designers should verify I2S or other host-interface compatibility, supported master or slave clocking, analog output capability, and regulator sequencing. Keep high-current digital and switching circuitry away from the codec's analog ball groups once the complete manufacturer layout guidance is available.
מומלץ
Connected Audio Terminal
The WM8350GEB/V is appropriate for a connected terminal that records through two analog inputs and drives two analog outputs from a digital-audio host. Its verified 12-bit stereo conversion and 48 kHz operation align with voice terminals, intercom endpoints, and connected control panels that do not require extended-frequency playback. The integrated power-management block can simplify rail coordination, but the engineer must confirm which internal rails are supplied externally and how startup behaves when the host enables the codec. A robust implementation should reserve local decoupling, provide a clean low-jitter clock, maintain analog and digital return separation, and use the manufacturer's BGA assembly and inspection requirements. Thermal and acoustic performance must be validated at the complete-system level rather than inferred from codec specifications alone.
מומלץ
Stereo Recording Module
A compact stereo recording module can use the WM8350GEB/V's two ADC channels to digitize left- and right-microphone or line-level inputs. The verified 48 kHz sampling rate supports voice, communication, and general-purpose capture, while 12-bit resolution determines the converter data format represented by the listing. The BGA package allows a dense module layout, but analog input conditioning, microphone biasing, anti-alias filtering, and clock cleanliness remain external design responsibilities. Engineers must verify input ranges, input impedance, channel mapping, digital-audio latency, and supported clock modes from the manufacturer datasheet. A short, quiet analog path and dedicated return plane are preferable to routing microphone signals beside digital clock and switching nets.
מומלץ
Industrial Control Panel Audio
An industrial control panel requiring audible prompts can place the WM8350GEB/V at the interface between a digital processor and an external speaker amplifier. The two DAC channels permit stereo monitoring, and the 48 kHz sampling rate is more than adequate for many voice-alert and interface sounds. Integrated power management may be useful where multiple audio rails are required, but industrial deployments must verify operating-temperature limits, supply tolerance, isolation expectations, and long-term availability. Because the verified data does not provide those limits, they must be resolved from the manufacturer datasheet before production release. Keep the codec away from motors, relays, and high-current switching stages, and validate the complete analog path for pop, noise, and thermal drift.
מומלץ
Embedded Speech Interface
The WM8350GEB/V can support embedded speech capture and playback in a host processor design that accepts 12-bit digital audio. Its two ADC channels allow simultaneous stereo or dual-microphone acquisition, while two DAC channels can support monitoring or local voice playback. The 129-BGA package is suitable for a multilayer, machine-placed design but not convenient for prototyping with a basic soldering station. Design teams should obtain the official pin map and recommended land pattern, verify the codec-driver requirements for the selected host, and assess clock jitter and word-signal integrity under actual processor load. A ground-reference partition between analog and digital sections can reduce coupling, provided it follows the manufacturer's layout instructions and avoids introducing ground-loop paths.

הערות תכנון
Use the official WM8350GEB/V 129-BGA land pattern rather than constructing one from the 7 x 7 mm package size. Confirm ball pitch, pin-1 location, exposed-feature geometry, solder-mask clearance, and assembly-process requirements against the manufacturer drawing. The supplied web data identifies the package but does not provide a complete ball map, so PCB implementation should remain blocked until the official pinout and footprint information are reviewed.
Separate analog input, analog output, digital-interface, and power-return routing as closely as the manufacturer's recommended layout permits. Keep codec clock and digital-audio traces away from microphone and line-input nets, and provide local supply bypassing at the relevant balls. Because the verified excerpt does not identify the exact supply rails or decoupling values, capacitor selection and placement must follow the manufacturer application guidance rather than generic audio-codec practice.
Do not treat every stereo audio codec as a drop-in replacement for the WM8350GEB/V. The target combines a 12-bit converter rating, 48 kHz operation, integrated power management, and a 129-BGA footprint; even a competitor with similar audio performance may use different pins, rails, clocking, and registers. Before substitution, compare every ball, supported clock mode, supply sequence, software-control requirement, and thermal feature against the official documentation.
