AK5572EN - 32-Bit 768kHz Stereo Audio ADC | AKM
料号： AK5572EN ✓ 量产中AK5572EN 概述
An audio ADC is a mixed-signal integrated circuit that converts differential analog audio signals into digital words for processing, storage, or transmission. The AK5572EN belongs to the ADC and DAC hierarchy within data-converter ICs and broader signal-chain semiconductors. Its stereo differential architecture supports balanced audio inputs, while selectable operating modes and interface formats provide flexibility across professional recording equipment, mixer consoles, USB audio interfaces, and premium home-audio equipment.
Key performance features include 32-bit conversion, a maximum sampling rate of 768kHz, 121dB dynamic range, and 112dB signal-to-noise-plus-distortion performance. The converter supports I2S digital audio, multiple TDM configurations, and DSD output up to 11.2MHz. According to the manufacturer product page and English datasheet, these capabilities position the device as a high-performance audio conversion solution with low-power operation and integrated filtering.
The AK5572EN includes four types of digital filters that can be selected according to the desired sound-quality preference. Its TDM support allows direct connection to DSPs, reducing external interface complexity in multichannel systems. MSB-first, two's-complement serial data and broad digital-interface selection make the device suitable for designs requiring flexible clocking and source synchronization.
Typical applications include digital mixers, multichannel recorders, premium USB audio interfaces, professional studio converters, and DSD-capable playback equipment. Analog signal integrity remains critical: differential routing, symmetrical inputs, careful clock layout, and a clean low-noise supply help preserve the converter's 121dB dynamic range. The 48-VFQFN exposed-pad package also requires a thermal-aware PCB layout to dissipate heat reliably.
When selecting a replacement, engineers should verify the complete pin definition, analog input range, clock topology, supported digital format, filter settings, control interface, and exposed-pad layout rather than relying on resolution and sample rate alone. The available cross-reference results do not establish a verified pin-to-pin substitute, so equivalent parts are not presented as drop-in alternatives.
This page combines verified manufacturer performance claims, source links, interface details, application guidance, and replacement-validation criteria. It distinguishes confirmed AK5572EN capabilities from electrical values that still require confirmation from the datasheet, providing more practical design guidance than a distributor listing alone.

典型应用
AK5572EN 适用于 6 应用s: Premium Digital Audio Mixer, Multichannel Studio Recorder, Professional USB Audio Interface, DSD-Capable Audio System, Digital Recording and Playback Console, High-End Home Audio Capture.
Premium Digital Audio Mixer
The AK5572EN fits premium digital mixer input channels because it combines two differential analog inputs with 32-bit conversion, 121dB dynamic range, and 112dB S/(N+D). Those figures provide ample margin for low-level program material and reduce the risk that quantization or converter noise will constrain the mixer's usable headroom. Its TDM capability can also reduce the number of separate digital links when the mixer routes multiple channels through a DSP. The design should use symmetric input routing, low-noise supplies, and clock traces that avoid digital switching regions. The four selectable digital filters allow system tuning, but the chosen filter must be coordinated with latency, out-of-band rejection, and the downstream DSP configuration.
推荐
Multichannel Studio Recorder
The AK5572EN is appropriate for a multichannel studio recorder where each board section requires high-resolution stereo conversion and a deterministic digital interface to a DSP. Its maximum 768kHz sampling rate accommodates high-resolution PCM workflows, while TDM support enables flexible channel interconnection according to the verified interface options. The 121dB dynamic range and 112dB S/(N+D) are particularly valuable when preserving quiet ambience, acoustic decay, and low-level detail. Layout must minimize converter-to-amplifier ground imbalance, keep clocks away from analog inputs, and provide adequate thermal spreading beneath the 48-VFQFN exposed pad. Firmware and hardware should be validated together because filter selection and data timing affect the final recording path.
推荐
Professional USB Audio Interface
The AK5572EN can serve as the high-performance capture ADC in a professional USB audio interface requiring stereo balanced inputs and extensive headroom. Its 32-bit format supports high-resolution PCM transfer, and the verified 121dB dynamic range exceeds the needs of many conventional music-production workflows. At 768kHz, the converter also supports specialized high-rate monitoring and acquisition requirements. The implementation should isolate the USB and digital-processing sections from the differential analog inputs, use a low-noise reference and supply arrangement, and control clock jitter through short, well-terminated routes. The exposed pad should be tied to the appropriate ground plane through a thermal and electrical layout that follows the manufacturer package guidance.
推荐
DSD-Capable Audio System
The AK5572EN is well suited to a DSD-capable conversion chain because it supports DSD output up to 11.2MHz while also providing conventional PCM conversion through interfaces such as I2S and TDM. This allows a system architect to share one analog-to-digital front end across high-resolution PCM and DSD workflows, provided the downstream digital equipment supports the selected format. The 32-bit architecture and 121dB dynamic range preserve the converter's premium positioning, but DSD implementation still requires careful clock generation, output-mode configuration, and firmware support. Analog input filtering, grounding, and supply-noise control remain essential because a high-resolution output format cannot recover information lost or contaminated upstream.
推荐
Digital Recording and Playback Console
The AK5572EN supports digital recording and playback consoles that combine balanced analog capture, format conversion, and DSP routing. Its stereo differential architecture allows each converter section to handle one balanced channel pair, while the 768kHz capability accommodates high-end recording formats. The four selectable digital filters provide system-level flexibility, and TDM can connect the converter efficiently to a central DSP. For a console, the analog sections should remain physically separated from switching power and high-current output stages, with star-grounding or ground-plane partitioning chosen according to the complete board architecture. Thermal performance is also relevant because the 48-VFQFN exposed pad must dissipate heat without creating a ground-current path through sensitive audio inputs.
推荐
High-End Home Audio Capture
The AK5572EN can be used in a high-end home-audio capture system where balanced stereo recording, high dynamic range, and high-resolution playback are priorities. Its 121dB dynamic range provides comfortable margin for capturing quiet acoustic passages, while 32-bit conversion at rates up to 768kHz supports archival and mastering workflows. I2S offers a straightforward connection to a digital audio transport, whereas TDM can serve more elaborate multichannel arrangements. Practical implementation requires a quiet analog front end, low-noise power conversion, a stable master clock, and isolation from motor or display-switching noise. The exposed pad and signal ground should be designed together so that thermal-current paths do not modulate the differential input reference.

设计说明
Keep the two analog inputs symmetric and route them away from digital clocks, switching-regulator nodes, display interfaces, and other high-current paths. Place analog decoupling and filtering components close to their associated AK5572EN pins using the manufacturer reference layout as the authority. For a differential signal chain, maintain matched geometry and impedance because unequal routing can degrade the common-mode rejection and noise performance promised by the converter's 121dB dynamic range.
Treat master, serial, and frame clocks as high-speed signals even at relatively low audio sample rates. Use short routes, continuous reference planes, deliberate return paths, and termination or series damping where the datasheet interface timing requires it. Avoid crossing digital clock nets over the differential analog inputs. Confirm clock polarity, data timing, MSB-first ordering, and the selected TDM or I2S configuration against the latest manufacturer datasheet before releasing the PCB.
The AK5572EN is supplied in a 48-VFQFN package with an exposed pad. Provide the manufacturer-recommended thermal-via pattern and connect the pad to the appropriate ground plane so that heat can spread without introducing unacceptable ground noise. Review the exposed-pad current path and keep high-current return currents from flowing beneath the sensitive analog section. Exact pad dimensions and via geometry must be taken from the package drawing rather than estimated.
Do not treat equal resolution as proof of interchangeability. A substitute must match the 48-VFQFN land pattern, every power and ground connection, analog input range, clock requirements, control pins, digital timing, filter behavior, and exposed-pad layout. The supplied cross-reference results did not verify a pin-compatible alternative, so board revisions should not substitute a generic 32-bit ADC without a manufacturer-supported pin and timing comparison.
