AK4395VF 24-Bit 192kHz Stereo DAC | Asahi Kasei
MPN: AK4395VF ✓ فعالAK4395VF جائزہ
An audio DAC is the final digital-to-analog conversion stage in a playback chain. It converts I2S-formatted digital samples into left and right analog voltages suitable for headphone or line-output amplifiers. Within the component hierarchy, the AK4395VF is an audio DAC, which belongs to the broader ADC/DAC and signal-conversion IC category used in digital audio equipment.
The principal features include 24-bit data resolution, a maximum sampling frequency of 192 kHz, stereo operation, I2S digital audio input, a 5 V supply, and digital-filter stopband attenuation of at least 110 dB. The high stopband attenuation is significant because it suppresses out-of-band noise and aliasing energy that could otherwise appear near the audio baseband after digital-to-analog conversion.
Internally, the AK4395VF combines a 24-bit digital filter with a multibit delta-sigma conversion architecture. The digital filter provides sharp transition characteristics for high-resolution PCM streams, while the stereo converter produces separate left- and right-channel analog outputs. This combination targets applications requiring faithful reproduction of 44.1 kHz, 48 kHz, 96 kHz, 176.4 kHz, and 192 kHz source material, subject to the interface and system clock implementation.
Typical applications include high-resolution DVD-Audio players, premium CD and network-audio players, digital audio decoding boards, professional audio interfaces, and two-channel headphone or line-output stages. The 192 kHz capability is particularly relevant to studio masters and archival playback systems, while the 110 dB or greater filter attenuation helps reduce wideband aliasing noise.
The 28-VSOP package requires a stable, low-noise 5 V supply and careful analog-output routing. Keep digital and analog return paths separated, use short traces around the converter, and follow the manufacturer pin-description and application-circuit tables when assigning power, ground, clock, and I2S signals. The exact pinout, output topology, and external component requirements should be taken directly from the AK4395VF datasheet.
This page organizes the AK4395VF product information into a technical summary, application guidance, specification comparisons, and practical design notes. It is intended to help engineers identify the correct resolution, sampling-rate, interface, package, and supply requirements before integrating the converter into a high-resolution audio design.

عام استعمالات
AK4395VF کے لیے موزوں ہے 6 ایپلیکیشنs: DVD-Audio Player, High-Resolution Headphone Amplifier, Professional Two-Channel Audio Interface, Network Audio Player, Digital Audio Decoder Board, Studio Master Playback.
DVD-Audio Player
The AK4395VF is a natural fit for a DVD-Audio player because it supports 24-bit digital audio at sampling rates up to 192 kHz and includes a 24-bit digital filter. The filter’s stopband attenuation of at least 110 dB reduces wideband aliasing noise in high-rate playback modes. Place the converter between the transport’s digital audio output and the analog line-output stage, using a stable 5 V supply and the manufacturer clock and decoupling recommendations.

High-Resolution Headphone Amplifier
The AK4395VF can form the conversion stage of a premium headphone amplifier driven by an I2S digital source. Its 24-bit resolution and 192 kHz sampling capability preserve high-rate source material, while the digital filter provides at least 110 dB stopband attenuation. The analog outputs can feed a suitably selected line or headphone driver, provided routing follows the datasheet output configuration and maintains a clean return path to the converter.

Professional Two-Channel Audio Interface
A professional monitoring interface can use the AK4395VF when it requires a stereo DAC with 24-bit resolution and support for rates through 192 kHz. The I2S interface supports integration with digital audio processors, while the 5 V supply and 28-VSOP package suit compact custom boards. Designers should verify master and slave clock behavior, output loading, and analog filtering against the manufacturer application circuit before finalizing the signal chain.

Network Audio Player
The AK4395VF is suitable for a high-resolution network audio player that receives PCM data from a digital audio processor and needs a dedicated stereo conversion stage. Supporting I2S and rates up to 192 kHz allows the playback path to handle high-rate music files when the upstream processor and clock architecture support them. Use local decoupling and controlled analog routing to prevent digital clock activity from degrading the stereo output.
تجویز کردہ
Digital Audio Decoder Board
The AK4395VF can be used on a modular digital audio decoder board where an I2S source must be converted into left and right analog signals. Its 24-bit processing and operation up to 192 kHz fit high-resolution transport and decoding platforms, while the 110 dB-or-greater digital-filter stopband attenuation helps suppress aliasing energy. The board layout should isolate converter clock and digital signals from the sensitive analog output section.
تجویز کردہ
Studio Master Playback
The AK4395VF is appropriate for a two-channel studio master playback path requiring 24-bit data at rates up to 192 kHz. The high attenuation of the integrated digital filter is useful when preserving the spectral purity of high-rate PCM material before the final line stage. The converter should receive a jitter-controlled clock, stable 5 V power, and a carefully laid-out analog output network to maintain playback fidelity.

ڈیزائن نوٹس
Use a stable 5 V analog and digital supply arrangement for the AK4395VF, and place the manufacturer-recommended decoupling capacitors directly beside the corresponding supply pins. Keep the converter’s digital return current out of the analog output reference path. Adequate local supply impedance control is especially important when the I2S source, clock circuitry, and analog output stage operate simultaneously.
Separate the 192 kHz-capable I2S and clock traces from the left and right analog outputs. Route clock signals away from output components, use a continuous ground reference under the converter where the package permits, and keep analog output traces short. These steps reduce the chance that digital switching activity will couple into the stereo output and degrade channel separation or noise performance.
Do not substitute the AK4393VF or AK4396VF for the AK4395VF solely because they belong to the same product family. The AK4393VF is associated with 96 kHz operation, while package and configuration requirements must also be checked for every proposed substitute. A valid board replacement requires the same 28-VSOP footprint, compatible pin assignment, matching 5 V supply arrangement, and acceptable clock and analog-output characteristics.
