AK4452VN - 32-Bit 2ch Premium Audio DAC | AKM
部品番号: AK4452VN ✓ 生産中AK4452VN 概要
An audio DAC converts digital PCM or DSD streams into an analog voltage suitable for amplification, loudspeakers, headphones, or audio analog-to-digital converters. The AK4452VN belongs to the digital-to-analog converter hierarchy within signal-chain and mixed-signal semiconductor devices. Its premium positioning is intended to preserve fine signal detail while supporting modern high-resolution playback formats.
The verified product information identifies a 32-bit resolution, two-channel architecture, 115 dB dynamic-range figure, 768 kHz maximum PCM input rate, 11.2 MHz maximum DSD input rate, and I2S digital audio input. The 32-QFN 5x5 mm package supports compact implementation in premium audio equipment. These features position the device for hi-fi playback, professional monitoring, network streamers, and automotive infotainment systems.
The AK4452VN uses eight channels of AKM's VELVET SOUND architecture and 32-bit digital filter processing. The manufacturer describes this combination as an implementation of low-distortion technology intended to improve sound detail and channel consistency. The digital interface supports both high-rate PCM and direct-stream digital sources, allowing one converter to cover conventional CD-rate audio as well as modern high-resolution PCM and DSD material.
Typical applications include network audio players, USB-DAC products, car audio systems, premium home-theater equipment, digital mixers, and studio monitoring. In each case, the converter can accept high-resolution digital sources while presenting an analog output to the downstream amplifier or analog signal-chain stage. The component's two-channel organization is especially appropriate for stereo audio rather than multichannel cinema decoding.
Designers should evaluate the analog output implementation, supported digital formats, clocking requirements, grounding, and power-supply arrangement against the complete datasheet before layout. The verified data does not specify output topology, reference voltage, supply rails, or detailed decoupling values, so those implementation details must not be inferred from the distributor summary alone.
This page consolidates the verified manufacturer and distributor information, distinguishes confirmed capabilities from unavailable specifications, and highlights the need for a complete datasheet review. It also records the absence of verified cross-brand drop-in equivalents instead of presenting functional substitutes as true pin-compatible replacements.

主な用途
AK4452VN の用途: 6 件s: High-Resolution Network Audio Player, USB Desktop DAC, Premium Automotive Audio Head Unit, Studio Monitoring DAC, Digital Mixing Console Output Stage, Premium Home Theater Stereo Preamp.
High-Resolution Network Audio Player
The AK4452VN fits a premium network audio player because its verified 32-bit resolution, 768 kHz PCM capability, 11.2 MHz DSD support, and 115 dB dynamic range cover modern high-resolution source formats. The I2S interface allows digital audio received by a network or USB-capable streaming module to reach the DAC without conversion to an intermediate format. Its 32-QFN 5x5 mm package also supports compact board layouts where space is constrained. The analog output then feeds the player's volume-control and amplifier stages. Before layout, verify the required master clock, digital filter mode, analog output topology, reference voltage, and decoupling values in the complete manufacturer datasheet.
おすすめ
USB Desktop DAC
The AK4452VN is appropriate for a desktop USB-DAC design requiring high-resolution stereo conversion. The verified I2S input accommodates digital streams delivered by a USB audio interface, while support for PCM rates up to 768 kHz and DSD up to 11.2 MHz provides broad format headroom. Its two-channel structure suits left and right headphone or line outputs, and the 115 dB dynamic-range figure is relevant to low-level audio material. In implementation, the USB interface clock, supported sampling-rate table, digital filter settings, and ground-return strategy must be validated together to prevent synchronization or format errors.
おすすめ
Premium Automotive Audio Head Unit
The AK4452VN can serve as the stereo conversion device in a premium automotive audio head unit because it supports 32-bit audio, 768 kHz PCM, 11.2 MHz DSD, and a compact 32-QFN 5x5 mm package. The 115 dB dynamic-range figure is useful when preserving quiet musical detail through the vehicle's analog amplification stage. I2S connectivity permits integration with a digital audio source or vehicle audio processor. Designers should still confirm AEC-Q100 qualification, automotive temperature limits, supply requirements, startup behavior, and electromagnetic compatibility because those details are not confirmed by the supplied product summaries.
おすすめ
Studio Monitoring DAC
The AK4452VN aligns with a stereo studio-monitoring DAC because its 32-bit processing, 768 kHz PCM support, 11.2 MHz DSD capability, and 115 dB dynamic range provide substantial resolution and signal-range headroom. The I2S interface can receive digital audio from a workstation, digital console, or dedicated audio interface, and the dual-channel topology maps naturally to left and right monitor outputs. Its 5x5 mm QFN package can simplify compact converter boards. For critical studio use, engineers should verify the actual THD+N across output levels, the analog output architecture, whether an external reference is required, and the supported digital-filter modes in the complete datasheet.
おすすめ
Digital Mixing Console Output Stage
The AK4452VN is relevant to the stereo output stage of a digital mixing console because it converts high-resolution digital channels with a verified 115 dB dynamic-range figure. A digital mixer or DSP can provide I2S streams at the supported PCM or DSD rates, allowing the DAC to preserve source resolution through the analog output section. The 32-QFN 5x5 mm package supports dense console electronics, although thermal and routing constraints still require careful placement. Engineers must confirm whether the console source supports the converter's required sampling modes and should evaluate output loading, grounding, clock distribution, and analog filtering according to the manufacturer reference circuit.
おすすめ
Premium Home Theater Stereo Preamp
The AK4452VN can be used in a premium stereo preamplifier or two-channel home-theater processor when the design accepts I2S digital audio and requires high-resolution conversion. The verified 32-bit architecture supports PCM data up to 768 kHz and DSD up to 11.2 MHz, while the 115 dB dynamic-range figure is useful for preserving quiet passages before volume control and power amplification. Its compact 32-QFN package leaves board area for analog processing. The implementation must account for channel mapping, supported audio-word lengths, clock mode, digital-filter selection, output reference, and whether the downstream amplifier requires balanced or unbalanced analog drive.

設計ノート
Follow the manufacturer reference layout for the 32-QFN 5x5 mm package. Place the DAC close to its digital source and analog output stage, minimize analog trace length, and provide an uninterrupted ground reference. Because the supplied web excerpts do not include the numbered pinout or exposed-pad connection, engineers must reproduce the complete land pattern, thermal-pad treatment, and component placement from the official datasheet rather than relying on a generic QFN footprint.
Validate the I2S clocking arrangement for every required format, including PCM up to 768 kHz and DSD up to 11.2 MHz. The verified summaries do not specify master-clock ratios, supported word lengths, or DSD transport mode. Check the AK4452VN format table and interface timing diagrams, maintain short clock and data routes, and avoid routing high-speed digital signals across the analog output region.
Use the supply rails, bypass capacitors, analog reference, and grounding arrangement specified in the manufacturer application circuit. The verified distributor material does not provide those values, so no capacitor size or regulator choice should be guessed. Confirm startup sequencing, analog-output muting behavior, and the relationship between the reference supply and digital supply before releasing a PCB for production.
Do not equate high supported sampling rates with automatic system compatibility. The source interface must provide the correct clock, data width, framing, and DSD mode. Also verify the selected digital-filter mode against analog bandwidth and clock requirements. A complete replacement decision requires comparing package drawings, terminal assignments, output topology, filter behavior, and electrical limits between the original and proposed part.
コンプライアンス情報
