AK4432VT - 32-Bit 192kHz Stereo Audio DAC | Asahi Kasei
部品番号: AK4432VT ✓ 生産中AK4432VT 概要
An audio DAC is a converter that transforms digital audio samples into analog voltage signals suitable for headphone amplifiers, line outputs, speakers, and other audio stages. Within the signal-chain hierarchy, the AK4432VT is an audio DAC, a digital-to-analog converter, an interface IC, and ultimately a semiconductor. It sits between a digital audio source and an analog output stage, where accurate conversion and low-noise analog output are central to sound quality.
Key features include 32-bit resolution, support for sampling rates up to 192 kHz, 108 dB dynamic range, and two-channel operation. The manufacturer describes the converter as using AKM's VELVET SOUND architecture and a newly developed 32-bit digital filter designed to provide short group delay. Single-ended SCF outputs are intended to improve performance in systems where clock jitter would otherwise degrade conversion quality.
The AK4432VT operates from a 3.0 V to 3.6 V supply, covering both its analog and digital operating requirements. The supplied manufacturer information identifies the device as an advanced audio DAC with two channels and I2S data input. Its 16-TSSOP surface-mount package supports compact digital audio products while providing separate digital and analog supply connections for careful PCB partitioning.
Typical applications include high-end CD and network audio players, digital music systems, home-theater audio equipment, professional monitoring products, and other stereo DAC designs requiring 192 kHz support. In each case, the AK4432VT converts incoming I2S data into analog signals that can be passed to an output amplifier, analog volume-control stage, or line-level driver.
A critical design consideration is maintaining a low-jitter digital clock source and separating analog and digital return paths appropriately. Power and ground routing should follow the manufacturer datasheet's recommended application circuit, while output-stage and filtering choices must preserve the converter's intended signal integrity. Exact pin assignments and external component values must be taken from the manufacturer datasheet rather than inferred from the package outline.
This product record combines verified manufacturer specifications, distributor availability, package information, pricing, application guidance, and a drop-in replacement assessment. It distinguishes documented AK4432VT-E2 compatibility from unverified functional alternatives and identifies all unavailable electrical details explicitly instead of estimating them.

主な用途
AK4432VT の用途: 6 件s: High-Resolution Network Audio Player, Premium CD and Digital Music Player, Home-Theater Audio DAC, Professional Audio Monitoring, Digital Music Instrument and USB Audio, Digital Mixing and Signal-Conversion Equipment.
High-Resolution Network Audio Player
The AK4432VT fits a high-resolution network audio player because it accepts 32-bit I2S audio and supports sampling rates up to 192 kHz while providing 108 dB dynamic range. It can be placed after the network transport or digital audio processor, with the digital section feeding its I2S inputs and the two single-ended SCF outputs feeding a low-noise analog output stage. This arrangement retains source resolution at the DAC boundary while providing more dynamic range than a conventional lower-resolution converter. In a jitter-sensitive system, the design should use a low-jitter clock source, keep digital clock traces short, and follow the manufacturer application circuit for analog and digital supply separation.
おすすめ
Premium CD and Digital Music Player
The AK4432VT is appropriate for premium CD and digital music players that require a stereo conversion stage with 192 kHz capability. Its 32-bit digital filter supports high-resolution digital audio, while the 108 dB dynamic range preserves quiet passages and low-level musical detail. The converter is normally placed between the digital transport and an I2S-compatible audio controller, followed by a headphone or line amplifier. Compared with using the source device's internal converter, a dedicated AK4432VT can provide controlled routing and a cleaner analog output section. The practical benefit depends on low-jitter clocks, stable 3.0 V to 3.6 V operation, and careful grounding rather than simply on the headline resolution rating.
おすすめ
Home-Theater Audio DAC
The AK4432VT can serve as the stereo DAC in a home-theater preamplifier or digital audio processor that receives 32-bit I2S streams. Its two-channel output architecture maps directly to left and right channels, while operation up to 192 kHz supports high-resolution movie and music sources. The single-ended SCF outputs should feed a low-noise analog gain and line-output stage. A primary design benefit is the combination of 108 dB dynamic range and short-group-delay digital filtering, which supports faithful playback of low-level content. Engineers should maintain analog and digital supply partitioning, provide local bypass capacitance as recommended, and verify the complete output-filter and clock topology from the manufacturer datasheet.
おすすめ
Professional Audio Monitoring
The AK4432VT is suitable for professional stereo monitoring products that require 32-bit digital audio and up to 192 kHz conversion. Its 108 dB dynamic range supports monitoring applications where low-level detail must remain visible, and its two SCF outputs simplify balanced or unbalanced analog stage design when followed by suitable output circuitry. The DAC should be driven by a stable, low-jitter audio clock and paired with carefully selected analog output filters. Unlike a generic consumer DAC, the AK4432VT provides a documented 3.0 V to 3.6 V operating range and -40°C to +105°C temperature capability, allowing use in controlled industrial or professional environments. Compliance requirements for any specific deployed standard still need separate verification.
おすすめ
Digital Music Instrument and USB Audio
The AK4432VT can form the stereo output stage of a USB or digital music device when the upstream controller provides compatible 32-bit I2S data. Its 192 kHz maximum sampling rate covers high-resolution playback, and the two-channel output aligns with typical left-right audio paths. The converter should sit close enough to the digital interface to limit clock-route sensitivity, while analog traces and ground returns should follow the manufacturer reference layout. Compared with a lower-rate DAC, it retains more source-word depth and accommodates more demanding hi-res formats. Because the supplied data does not state USB clock, latency, or power-consumption figures, the design must use the full AK4432 datasheet to validate the interface boundary before layout release.
おすすめ
Digital Mixing and Signal-Conversion Equipment
The AK4432VT is appropriate for digital mixers and signal-conversion equipment that need a high-quality stereo analog output from digital sources. Its two-channel 32-bit architecture and 108 dB dynamic range allow it to convert an I2S mix bus into analog signals for monitoring or downstream processing. SCF outputs provide a defined starting point for the analog stage, while the short-group-delay digital filter supports responsive monitoring workflows. The converter must still be paired with an appropriate analog output amplifier and the source must support compatible framing and clocking. A key engineering benefit is that a single dedicated DAC can centralize final conversion quality, but its 3.0 V to 3.6 V supply range and exact I/O timing must be reconciled with the rest of the system architecture.

設計ノート
Route the AK4432VT's analog and digital supply connections according to the manufacturer application circuit, using the documented 3.0 V to 3.6 V operating range. Place the required bypass capacitors at their designated pins and minimize supply-loop area. Keep digital switching currents away from the analog output and SCF reference paths. Because the supplied information does not include current consumption, output impedance, or permitted supply ripple, those values must be taken from the datasheet before capacitors and regulators are selected.
Treat the master clock and I2S data lines as high-fidelity signals. Keep them short, route clock and data away from analog outputs, and avoid introducing stubs or unnecessary test pads. Maintain a continuous ground plane and follow the manufacturer's separation of analog and digital return currents. The device's single-ended SCF outputs are intended to reduce clock-jitter sensitivity, but that benefit cannot compensate for a noisy clock source or poor return-path design.
Do not infer pin functions from the 16-TSSOP package alone. The verified data establishes the package and operating range but does not provide the complete numbered pin table, so the AK4432VT datasheet must be used for power pins, grounds, clock inputs, I2S data, mode controls, and SCF outputs. Also verify AK4432VT-E2 markings, lifecycle, and full electrical limits before approving it as a production substitute.
Use a low-jitter clock source and preserve the required relationship between the audio master clock, system clock, and I2S data. The AK4432VT's SCF outputs can improve conversion performance in systems with excessive clock jitter, but correct source-device configuration remains essential. Confirm supported clock modes and sample-rate ratios from the manufacturer datasheet rather than assuming that every 32-bit I2S source is directly compatible.
コンプライアンス情報
The supplied verified data does not explicitly provide RoHS, REACH, lead-free, halogen-free, or conflict-minerals declarations for AK4432VT. AEC-Q100 is not applicable because the component is an audio DAC rather than an automotive-grade device.
