AK5386VT - 24-Bit 216kHz Stereo Audio ADC | Asahi Kasei
MPN: AK5386VT ✗ סוף ייצורAK5386VT סקירה
An audio ADC is a mixed-signal data-converter IC that transforms left and right analog audio signals into digital sample data. Its place in the product hierarchy is audio ADC → delta-sigma ADC → data converter → analog and mixed-signal IC. This conversion allows audio equipment to preserve waveform information for processing, transmission, recording, playback, and digital storage.
The AK5386VT implements Enhanced dual-bit delta-sigma techniques to balance conversion resolution, sampling performance, and implementation cost. Its 24-bit word length supports high-resolution professional and consumer audio systems, while the 8 kHz lower sampling limit accommodates voice-band content. The 216 kHz upper limit supports high-rate digital audio acquisition and processing. A 16-TSSOP package supports compact, surface-mount PCB layouts.
The device includes separate left and right single-ended analog inputs and an I2S digital interface. Its 3.3 V and 5 V supply options provide flexibility in audio systems that use either conventional or lower-voltage digital logic. Because the AK5386VT performs both channels in one package, it can reduce component count and simplify synchronization between stereo channels. Clocking, digital-audio format, and analog front-end requirements must still be checked against the manufacturer pin description and timing diagrams.
Typical applications include professional audio conversion, multichannel recording equipment, digital mixing consoles, consumer-audio interfaces, sound-card analog front ends, and instrumentation requiring high-resolution audio capture. The wide sampling-rate range also supports applications spanning voice, CD-rate audio, professional multirate conversion, and high-resolution acquisition.
For a new design, treat analog and digital grounding, clock jitter, input-level range, and the external anti-alias or acquisition circuitry as system-level requirements. Follow the manufacturer reference circuit for capacitor values and supported input configurations. Confirm that the host controller can generate the required master clock and accept the converter's I2S-compatible output before finalizing the PCB and firmware interface.
This page organizes the AK5386VT specifications, interface considerations, application guidance, comparison parameters, and design notes into one engineering-focused reference. It also distinguishes verified drop-in replacements from parts that are only functionally similar, helping designers make PCB and sourcing decisions without confusing equivalent conversion capability with pin compatibility.

יישומים טיפוסיים
AK5386VT מתאים עבור 6 יישוםs: Professional Audio Recording, Digital Mixing Console, Consumer Audio Interface, High-Resolution Audio Capture, Digital Sound Card, Voice and Broadcast Equipment.
Professional Audio Recording
The AK5386VT fits professional recording front ends that require 24-bit stereo conversion across a broad sampling-rate range. Its 8 kHz-to-216 kHz span accommodates voice capture, conventional audio rates, high-resolution recording, and oversampled acquisition. The two single-ended inputs provide one conversion channel for each stereo signal, while the I2S interface transfers synchronized digital samples to a recorder, DSP, or storage controller. Designers should establish the target input amplitude, clock architecture, and supported master-clock condition before laying out the analog and digital sections.
מומלץ
Digital Mixing Console
The AK5386VT can provide the stereo conversion stage for a digital mixing console that accepts analog line-level sources and routes them into a digital processing engine. Its 24-bit data format and maximum 216 kHz sampling rate support high-resolution console workflows, while dual-channel conversion keeps left and right paths together in one package. The I2S interface supports integration with digital audio processors, but the system clock, sample-rate changes, channel alignment, and ground-return strategy must be designed together to prevent synchronization and noise problems.
מומלץ
Consumer Audio Interface
The AK5386VT is applicable to compact stereo audio interfaces that convert analog consumer or professional sources into digital audio. Its 16-pin TSSOP package helps minimize board area, and its 8 kHz-to-216 kHz range permits one converter to cover several classes of source material. The 3.3 V or 5 V supply choices can simplify interface planning across different logic environments. A practical design must still include suitable input conditioning, stable clock generation, and careful separation between analog and digital return currents.
מומלץ
High-Resolution Audio Capture
The AK5386VT suits high-resolution capture systems where 24-bit samples and rates as high as 216 kHz are useful for preserving detailed audio information. The Enhanced dual-bit delta-sigma architecture supports accurate conversion of two single-ended channels, and the I2S output can feed a DSP or storage device. Engineers should account for analog bandwidth, anti-alias filtering, clock jitter, and supported conversion modes. Digital signal integrity depends on keeping the data and clock traces short while maintaining a controlled return path.
מומלץ
Digital Sound Card
The AK5386VT can form the analog front end of a stereo digital sound card connected to a host processor. Its two channels support conventional left and right capture, while rates from 8 kHz to 216 kHz provide flexibility for communication, multimedia, and high-resolution audio workloads. The host must generate a valid master clock and receive I2S-compatible data with the expected polarity and framing. Analog input conditioning and digital clock routing should be reviewed together so switching activity does not degrade the captured signal.
מומלץ
Voice and Broadcast Equipment
The lower end of the AK5386VT sampling range makes it relevant to voice acquisition, monitoring, and broadcast equipment that also needs higher-rate audio capability in the same converter family. The 24-bit word length provides headroom for downstream processing, and the dual-channel structure supports stereo program or auxiliary channels. For broadcast and communication equipment, clock jitter, analog-to-digital isolation, grounding, and regulatory requirements may dominate the final architecture. Use the manufacturer reference circuit as the starting point for supported input and filtering arrangements.

הערות תכנון
Separate analog input routing from the I2S clock and data path, and provide a direct, low-impedance ground return beneath the converter and its decoupling network. Place the required input, reference, and bypass capacitors close to their designated pins using short traces. Follow the manufacturer reference layout for component values and topology. Do not route digital return current beneath the analog input area, because shared return paths can convert switching activity into input-referred noise.
Treat the converter master clock and I2S data as a matched clock-data interface. Route both through a common, continuously referenced ground plane, avoid long stubs, and keep the source and return paths together. Check the host processor's clock output and data-edge timing against the manufacturer timing diagrams. If the clock source is distant, evaluate series damping and consider a low-jitter clock arrangement rather than relying on a long board trace.
Confirm the full-scale input range, analog input configuration, supported master-clock condition, and digital-audio format before populating the PCB. Changing supply voltage, sample rate, or clock mode can alter the required external component network and valid operating conditions. Use the AK5386VT pin-description table for every connection, and verify that the selected input path matches the single-ended architecture rather than applying a generic dual-differential converter schematic.
