AK5552VN - 32-Bit 768kHz Stereo Audio ADC | AKM
Référence : AK5552VN ✗ Fin de vieAK5552VN Présentation
An audio ADC is a specialized data-converter IC that converts analog audio signals into digital PCM or DSD data. In the broader semiconductor hierarchy, the AK5552VN belongs to the analog-to-digital converter class, supports digital audio applications, and operates as a signal-chain device between analog preamplification and digital audio processing. Its differential inputs help reject common-mode noise while preserving low-level audio information.
Key features include 32-bit conversion, a maximum sampling rate of 768 kHz, two differential input channels, and four selectable digital filters. According to the manufacturer product page, the converter achieves 115 dB dynamic range and 106 dB signal-to-noise-plus-distortion while maintaining low power-consumption performance. These characteristics target high-resolution recording and mixing systems rather than general-purpose low-cost conversion.
The AK555x family uses configurable digital filtering to accommodate different sound-source requirements. The verified manufacturer description states that four filter types are integrated and selectable according to the source. Differential input architecture also allows balanced analog connections, which can reduce susceptibility to ground-potential differences and interference when paired with suitable front-end circuitry.
Typical uses include professional mixers, multi-channel recorders, digital audio workstations, high-resolution capture equipment, and digital recording systems. At 768 kHz sampling, the converter can support high-resolution PCM workflows and DSD-compatible audio architectures identified in distributor product listings.
Designers should treat the ADC as a high-performance analog signal-chain component rather than a generic data converter. Input gain, common-mode voltage, clocking, digital interface configuration, filter selection, grounding, and decoupling all influence achievable performance. The manufacturer datasheet should be used to verify complete pin assignments, supported output modes, supply requirements, and application-specific layouts.
This page combines verified manufacturer and distributor information with practical sourcing, application, and comparison guidance. It also distinguishes confirmed drop-in substitutes from devices that merely share the broad audio-ADC category, preventing a functional alternative from being mistaken for a PCB-compatible replacement.

Applications typiques
AK5552VN convient pour 6 applications: Professional Digital Mixing Console, High-Resolution Multi-Channel Recorder, Digital Audio Workstation, Studio Monitor Controller, Digital Recording and Playback System, High-End Audio Interface.
Professional Digital Mixing Console
The AK5552VN fits professional mixing-console input channels because its two differential inputs support balanced audio connections while 32-bit conversion and 115 dB dynamic range preserve low-level program material. The 768 kHz maximum sampling rate also supports high-resolution capture workflows. Its four selectable digital filters allow the system to adapt to different sound sources without changing the analog front end. In implementation, the converter should sit near the preamplifier and digital routing circuitry, with controlled return paths for clock and data signals. Exact input range, common-mode voltage, clock format, and decoupling must follow the manufacturer datasheet.
Recommandé
High-Resolution Multi-Channel Recorder
The AK5552VN is appropriate for multi-channel recorders that need high-resolution stereo capture, differential analog connectivity, and support for sampling rates as high as 768 kHz. Its 115 dB dynamic range and 106 dB S/(N+D) are valuable when preserving quiet passages and reducing audible conversion artifacts. Two channels per converter allow a board to scale by adding matched converter and clock sections. The design must maintain signal integrity from balanced inputs through the ADC and across the digital bus, so grounding, clock distribution, and trace routing should follow the manufacturer reference guidance.
Recommandé
Digital Audio Workstation
The AK5552VN can serve as a capture converter in a digital audio workstation requiring 32-bit precision and operation up to 768 kHz. Its differential inputs reduce sensitivity to common-mode disturbance when the converter is connected to a balanced analog front end, while four selectable filter types provide source-dependent processing options. In a workstation, the ADC should be grouped with the audio processor, clock source, and digital interface to minimize bus timing risk. Verify supported PCM and DSD output modes and all supply requirements in the manufacturer datasheet before fixing the system clock architecture.
Recommandé
Studio Monitor Controller
The AK5552VN can be integrated into a studio monitor controller that digitizes balanced monitoring or return channels before processing and routing. The 115 dB dynamic range supports preservation of low-level signals, while the two differential channels align naturally with a stereo monitor architecture. Its four selectable digital filters allow system designers to match conversion behavior to different program material or source characteristics. Placement near the input connector and balanced receiver is important because long analog traces can undermine the benefit of differential inputs. The manufacturer guidance should govern input filtering, reference voltage, clocking, and exposed-pad layout.
Recommandé
Digital Recording and Playback System
The AK5552VN is suitable for a digital recording system that must capture stereo audio at high resolution and potentially use DSD-oriented data paths. Its maximum 768 kHz sampling rate, 32-bit output, and selectable filters support flexible high-fidelity recording modes. The differential analog section should use controlled return paths and symmetric routing, while the digital outputs require a compatible clock and serial interface. Because the verified information does not enumerate every supported mode or timing condition, system engineers should use the manufacturer datasheet to select master-clock ratios, data widths, and filter settings before finalizing the PCB.
Recommandé
High-End Audio Interface
The AK5552VN fits a premium two-channel audio interface where balanced inputs, high dynamic range, and high-speed conversion are central requirements. The 32-bit architecture and 768 kHz capability support demanding PCM and DSD workflows, while the 106 dB S/(N+D) specification helps limit combined noise and distortion. Designers should place the converter close to its balanced input network and separate sensitive analog routing from digital clock and data lines. Power, reference, clock, and thermal details must be taken directly from the manufacturer datasheet because those values were not included in the verified product summaries.

Notes de conception
Place the AK5552VN close to the balanced analog input network and minimize the distance between the converter, its reference network, and the associated decoupling. Route the differential pair as a tightly coupled pair with a continuous reference plane. Keep high-current digital and clock paths away from the analog inputs, and use manufacturer-recommended grounding and exposed-pad connections because exact values were not included in the verified summaries.
Treat the clock and digital data lines as a coordinated high-speed interface rather than routing them independently. Use the manufacturer-supported clock mode and data timing, verify output impedance and trace loading, and provide return paths for high-speed edges. The AK5552VN supports sampling rates up to 768 kHz, but that headline rate alone does not establish a complete clock topology; supported master-clock ratios and timing conditions must be confirmed in the datasheet.
Do not substitute the AK5552VN solely because another device offers 32-bit resolution, two channels, or a similar sample rate. A valid replacement must match the 48-QFN 7 x 7 mm footprint, pin assignments, input common-mode range, supply arrangement, clock interface, supported digital formats, and filter behavior. No drop-in substitute was confirmed in the supplied cross-reference results, so a board revision should not be approved without a complete manufacturer-level comparison.
Informations de conformité
The supplied verified data does not state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status. AEC-Q100 is marked not applicable because the verified data does not identify this part as an automotive-qualified device.
