AK4396VF - 24-Bit Stereo 192kHz DAC | AKM | VSOP-28
料号： AK4396VF ✓ 量产中AK4396VF 概述
A digital-to-analog converter is an interface IC that converts digital audio samples into proportional analog voltages or currents. Within the signal-chain hierarchy, a DAC sits between a digital audio source and an analog output stage. The AK4396VF is a stereo DAC, meaning that one package provides two audio conversion channels for applications such as CD players, DVD-Audio systems, network-audio receivers, and premium consumer audio equipment.
The headline capabilities of the AK4396VF are 24-bit resolution, operation up to a 192 kHz sampling rate, and two-channel audio conversion. The 24-bit format provides substantially more code values than conventional CD audio, while the 192 kHz capability supports high-resolution digital audio sources. The advanced multi-bit delta-sigma implementation is intended to improve conversion performance while retaining the integration advantages of a compact mixed-signal IC.
The AK4396 is designed around separate analog and digital supply concepts, including dedicated reference and power-related connections. Its digital filter forms part of the signal path and requires the correct clocking and digital-audio interface configuration. The manufacturer documentation identifies the AK4396VF as a 28-pin VSOP device intended for surface-mount assembly, with an indicated operating temperature range of -40°C to +85°C.
Typical uses include high-resolution CD and DVD-Audio players, digital audio amplifiers, home-theater equipment, professional monitoring electronics, and multi-channel audio systems using multiple DAC channels or devices. In each case, the device requires a clean analog supply, appropriate reference voltage, compliant input clocks, and an output-stage design matched to the DAC’s analog outputs.
Designers should preserve the analog and digital grounding strategy specified by the manufacturer, place decoupling capacitors close to their associated supply pins, and treat the reference and analog-output nodes as sensitive paths. Clock source and filter configuration also determine whether the device operates in its intended audio mode. Consult the manufacturer’s pin-description and application sections before assigning tracks on a new board.
This product record combines the AK4396VF device description, family comparison information, package identification, and practical design guidance in one engineering-focused reference. It also distinguishes confirmed drop-in options from related converters that require additional compatibility verification.

典型应用
AK4396VF 适用于 6 应用s: High-Resolution DVD-Audio Player, Network Audio Receiver, Digital Audio Amplifier, Professional Audio Monitor Controller, CD and SACD Audio System, Premium Stereo Headphone DAC.
High-Resolution DVD-Audio Player
The AK4396VF fits a premium DVD-Audio player because it provides two-channel, 24-bit conversion with operation up to 192 kHz. It is positioned in the signal path after the transport or digital audio decoder and before the analog output stage. Using the device at 192 kHz requires a compatible master clock and audio interface, while the 24-bit digital filter must be configured according to the manufacturer guidance. Its two-channel architecture also maps directly to conventional stereo playback, reducing the number of DAC packages needed for a conventional left-right output architecture.
推荐
Network Audio Receiver
The AK4396VF is appropriate for a network audio receiver that accepts high-resolution digital streams and requires a clean stereo analog conversion stage. Its 192 kHz maximum sampling rate covers high-resolution source formats, while 24-bit resolution preserves the numerical depth of those streams. The receiver clocking system must deliver the required master and channel clocks, and the analog outputs should feed a carefully designed low-noise amplification stage. This arrangement is useful when separate transport, streaming, and conversion functions are needed.
推荐
Digital Audio Amplifier
A digital audio amplifier can use the AK4396VF to convert its digital input into analog audio before power amplification. The two-channel DAC supports 24-bit data and sampling rates up to 192 kHz, making it suitable for systems that preserve high-resolution source material through the signal chain. Its analog output and reference circuitry require careful layout to prevent converter noise from reaching the output amplifier. Clock synchronization and format compatibility must be verified between the digital input processor and the AK4396VF.
推荐
Professional Audio Monitor Controller
The AK4396VF can provide the stereo conversion stage in a professional monitor controller or rack-mounted digital audio interface. Its 192 kHz sampling-rate capability is useful when the system must handle high-resolution studio or mastering material, while 24-bit conversion preserves source precision. The implementation must maintain clean separation between digital and analog sections, provide a stable reference network, and route the converter outputs into the monitor amplification and gain-control stages. Verify input format and clock behavior during bring-up.
推荐
CD and SACD Audio System
The AK4396VF is suitable for a CD and high-resolution disc player that requires a stereo DAC capable of 192 kHz operation. It can replace lower-rate conversion stages in equipment intended to accept modern high-resolution digital sources while retaining a conventional two-channel analog output. The digital source must supply compatible audio data and clocks, and the analog section should use the manufacturer’s recommended reference and decoupling arrangements. This use also allows the same converter to cover conventional 44.1 kHz, 48 kHz, and higher-rate sources when supported by the system clocking.
推荐
Premium Stereo Headphone DAC
The AK4396VF can serve as the conversion element in a premium stereo headphone DAC. The 24-bit, 192 kHz capability preserves high-resolution digital inputs, while the two-channel architecture feeds left and right analog outputs into balanced or single-ended headphone amplification. Because headphone systems are sensitive to noise, reference routing, supply separation, and output grounding deserve careful attention. The AK4396VF should be paired with a low-noise output stage and verified for the required digital format, clock ratio, filter configuration, and output topology.

设计说明
Separate analog and digital return paths as closely as the manufacturer application circuit permits, and connect the device grounds using the documented topology rather than a generic star point. Keep the reference network, analog output traces, and their decoupling components away from master-clock and bit-clock routing. Treat the VSOP lead pitch as 0.65 mm and follow the package drawing for the land pattern and solder mask.
Assign separate low-impedance supply paths to the analog and digital sections, then place their local capacitors immediately across the relevant device pins. Use only the voltage and capacitance values specified in the manufacturer datasheet, including any capacitor tolerance or bias requirements. Check startup sequencing and ensure that every supply remains within the absolute maximum and operating limits for the selected production conditions.
Route master clock, bit clock, and left/right channel-clock signals away from analog outputs and the reference node. Provide a continuous ground reference beneath high-speed digital traces and avoid unnecessary stubs. Confirm the source device’s clock ratio, data alignment, bit order, and sampling-rate mode against the AK4396VF digital interface requirements before enabling the audio path.
合规信息
The AK4396VF is an audio converter IC, so AEC-Q100 qualification is not applicable. RoHS, REACH, lead-free, halogen-free, and conflict-minerals status require confirmation from the current manufacturer product documentation or declaration.
