WM8788GEDT - 24-Bit 192kHz Stereo Audio ADC | Cirrus Logic
N.º da peça: WM8788GEDT ✓ AtivoWM8788GEDT Visão geral
An audio ADC is an interface IC that converts left- and right-channel analog sound signals into digital samples for processing, storage, or transmission. The WM8788GEDT belongs to the broader ADC/DAC hierarchy, where an ADC converts analog audio into digital data and a DAC performs the inverse operation. Its stereo architecture supports simultaneous processing of two analog channels, while the digital interface carries 24-bit audio data.
The headline specifications are a 24-bit conversion resolution, a maximum sample rate of 192 kHz, and a 16-pin TSSOP package. The device accepts a pair of analog inputs, and external resistors configure the inputs for line-level operation at 1 Vrms or for higher signal levels. This combination makes the converter appropriate for consumer audio equipment, digital mixing systems, recording interfaces, and other stereo audio products that require high-resolution capture.
The verified interface data identifies I2S as the digital audio interface and indicates separate analog and digital supply sources. These supply domains require correct decoupling and grounding to prevent digital switching activity from contaminating the analog conversion path. The converter's operating range of -40°C to +85°C supports use across industrial and commercial temperature environments, subject to the complete manufacturer datasheet requirements.
Typical applications include high-resolution stereo recording, line-level audio capture, digital audio mixers, and audio interface products. Its 192 kHz maximum rate supports high-resolution conversion, while the 24-bit word length provides ample numerical resolution for professional and premium consumer audio. Designers should still verify clocking, supported audio-data formats, analog input scaling, and power sequencing against the manufacturer datasheet before releasing a PCB.
A key design consideration is analog-versus-digital layout isolation. Place the analog input network close to the converter, maintain a continuous ground reference, and isolate high-current digital return paths from the ADC inputs. Also confirm the exact 16-pin TSSOP pinout and exposed support requirements; the supplied search data does not include a verified pin-by-pin diagram.
This page combines verified manufacturer and distributor information with explicit data gaps, application guidance, sourcing context, and design considerations. It distinguishes documented facts from parameters that still require confirmation in the full WM8788GEDT datasheet, helping engineers make a more reliable preliminary design decision without presenting unsupported specifications as established data.

Aplicações típicas
WM8788GEDT é adequado para 6 aplicaçãos: High-Resolution Stereo Recording, USB Digital Audio Interface, Digital Audio Mixer, Consumer Hi-Fi Signal Capture, Industrial Audio Monitoring, Digital Instrument and Test Equipment.
High-Resolution Stereo Recording
The WM8788GEDT fits high-resolution stereo recording front ends because it provides 24-bit conversion resolution, a maximum sampling rate of 192 kHz, and I2S digital output. Its two analog inputs can be conditioned for 1 Vrms line-level signals or higher levels through external resistors, allowing the converter to sit behind a line input stage in a professional or premium consumer recorder. The digital output can feed a DSP or audio processor for storage and monitoring. Before final design approval, verify full-scale input, SNR, dynamic range, clock roles, and supported digital formats in the manufacturer datasheet, because those electrical values were not present in the supplied verified excerpts.
Recomendado
USB Digital Audio Interface
The WM8788GEDT is a candidate for the analog-to-digital section of a USB digital audio interface because it combines a 24-bit stereo ADC, up to 192 kHz sampling, and an I2S interface. The I2S output can connect to a USB audio controller or digital signal processor that handles USB transport, clocking, and user controls. The verified operating range of -40°C to +85°C also suits many commercial and industrial interface designs. System designers must still confirm master-clock requirements, supported sample-rate multiples, data alignment, supply voltages, and the exact pinout because these details are absent from the supplied search data.
Recomendado
Digital Audio Mixer
The WM8788GEDT can serve as the stereo analog capture section of a digital audio mixer, converting two line-level inputs at up to 192 kHz and delivering 24-bit stereo data over I2S. This is useful when the mixer architecture preserves high-resolution samples before gain staging, mixing, effects, and conversion to a playback format. External input resistors allow the analog scaling to be adapted for 1 Vrms or higher signal levels. The converter should be paired with a low-noise analog front end, and layout should keep sensitive input routing away from digital clocks and switching currents. Verify input impedance, reference requirements, and clocking from the full datasheet.
Recomendado
Consumer Hi-Fi Signal Capture
The WM8788GEDT is appropriate for a high-end consumer Hi-Fi capture path requiring 24-bit stereo conversion and I2S output at rates up to 192 kHz. It can digitize source components through line-level input conditioning and pass the resulting samples to a digital signal processor for volume, decoding, or playback-path control. The 16-TSSOP package supports compact surface-mount construction, although it is not among the smallest available audio-converter packages. A practical design must address analog and digital supply decoupling separately, preserve a quiet ground reference, and confirm the exact TSSOP pin arrangement before library and PCB release.
Recomendado
Industrial Audio Monitoring
The WM8788GEDT can be evaluated for industrial audio monitoring equipment requiring two-channel conversion over a -40°C to +85°C operating range. A 24-bit, 192 kHz-capable stereo ADC can capture instrumentation, machine, or environmental audio for later analysis by a digital processor. Because the verified listing confirms the operating range and active lifecycle status but does not provide accuracy, noise, or supply details, the device should remain provisional until those parameters are checked. Industrial implementations should also use robust input protection, carefully filtered analog supplies, isolated return paths where required, and thermal analysis of surrounding power circuitry.
Recomendado
Digital Instrument and Test Equipment
The WM8788GEDT is suitable for preliminary use in digital measurement equipment that captures two analog channels and needs 24-bit digital audio data for analysis, display, or recording. Its I2S output and maximum 192 kHz rate provide a straightforward connection to an embedded processor, while the 16-TSSOP package supports conventional surface-mount assembly. Instrument designers should account for analog input bandwidth, settling behavior, clock jitter, reference accuracy, and the relationship between conversion rate and measurement bandwidth. Those parameters were not available in the supplied excerpts, so the manufacturer datasheet must be used to qualify the device before a precision measurement design is released.

Notas de projeto
Keep the two analog input paths short and place their external scaling resistors close to the corresponding WM8788GEDT inputs. Route analog signals away from the I2S clock, data lines, digital supply return current, and any switching-regulator nodes. A continuous ground plane can reduce return-path discontinuities, but analog and digital currents should still be managed so switching current does not flow beneath the input traces. The verified data does not provide a reference PCB layout, so use the manufacturer application circuit and layout guidance as the controlling source.
Treat the analog and digital supplies as separate domains until the datasheet specifies otherwise. Place local high-frequency bypass capacitors at the supply and ground pins, with additional bulk capacitance near the converter and upstream regulator. Control rise time so that power-supply startup does not create an excessive input transient, and verify the acceptable supply ranges, sequencing rules, and maximum voltage before component selection. Exact capacitor values cannot be derived from the supplied excerpts because the supply-voltage and stability information is missing.
The I2S interface carries a 24-bit stereo stream at rates up to 192 kHz, so clock-edge quality and data alignment are central to reliable capture. Confirm whether the WM8788GEDT is master or slave, which clock edges are valid, and whether both channels share one data line or use separate lines. Provide a clean low-jitter master clock, match trace lengths where channel skew matters, and avoid routing clock signals across split planes. The exact digital timing and supported format must be taken from the manufacturer datasheet.
Do not infer the complete pinout or electrical ratings from the distributor package name alone. The verified information establishes a 16-pin TSSOP, analog and digital supply sources, I2S output, and externally scaled inputs, but it omits pin names, supply limits, SNR, dynamic range, and full-scale input. In particular, do not select resistor values solely from the stated 1 Vrms line-level mode. Review the manufacturer input-range table and application circuit, then verify the 16-TSSOP footprint and pin numbering against the actual datasheet revision.
Informações de conformidade
The supplied verified results do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals compliance. No compliance status has been inferred from the manufacturer or distributor names.
