AK5393VS - 24-Bit Stereo Audio ADC | AKM | Professional Audio
MPN: AK5393VS ✓ AktifAK5393VS Ringkasan
An audio ADC is an ADC specialized for converting left- and right-channel analog audio signals into high-resolution digital data. In the broader electronics hierarchy, the AK5393VS belongs to the ADC/DAC category, within analog-to-digital converters and digital audio interface ICs. Its role is to preserve amplitude and phase information during conversion while presenting a serial digital output to an audio processor, codec, transmitter, or storage system.
The AK5393VS supports 24-bit conversion, 128-times oversampling, dual-channel operation, and a 1 kHz to 108 kHz sampling-rate range. Its Enhanced Dual Bit architecture is intended to achieve a wide dynamic range while retaining distortion characteristics associated with high-resolution conversion. The 28-pin SOP package supports compact integration into professional audio equipment while providing separate connections for analog, digital, clock, and power functions.
The converter operates from a +5 V analog supply according to the manufacturer documentation. Input protection is important: analog input voltages must remain within the specified limits around the analog supply and ground, and current beyond 10 mA into AIN+ or AIN- should be avoided. These constraints make the analog front end, input routing, and grounding arrangement central to achieving the converter's intended performance.
Typical uses include professional digital audio equipment, broadcast consoles, studio recording interfaces, high-resolution multichannel converters, and digital audio processing modules. It can be paired with an audio codec, digital signal processor, FPGA, or microcontroller when the host must consume serialized 24-bit conversion data. The supported sampling range allows the same converter family to address low-rate broadcast-oriented paths and high-rate studio capture systems.
Design the analog input network so that gain staging and source impedance suit the AK5393VS input stage. Keep analog and digital return paths separated, place decoupling capacitors close to the supply pins, and use a low-jitter clock source because clock quality can affect conversion performance. Use the pin-description table and typical application circuit in the manufacturer datasheet when assigning traces and external components.
This product guide combines the verified AK5393VS specifications, package information, sourcing details, pin-compatible alternatives, comparison parameters, and practical layout guidance. It also identifies the principal design trade-offs among the available AKM converters so engineers can select a device based on channel count, resolution, sampling rate, package, and actual pin compatibility rather than family name alone.

Aplikasi Biasa
AK5393VS patut untuk 6 aplikasis: Professional Stereo Recording Interface, Broadcast Audio Console, High-Resolution Studio Capture, Digital Audio Processing Module, FPGA-Based Audio Capture, Multichannel Audio Conversion.
Professional Stereo Recording Interface
The AK5393VS fits a professional stereo recording interface because it combines two 24-bit conversion channels, 128-times oversampling, a sampling-rate range of 1 kHz to 108 kHz, and a specified dynamic range of 117 dB. It can convert balanced left- and right-channel audio from an input stage and provide serialized data to an audio codec, DSP, or FPGA. The principal design benefit is a high-resolution conversion function in a compact 28-pin SOP package. Designers should still account for the +5 V analog supply, preserve the specified AIN+ and AIN- voltage limits, and control clock jitter to avoid degrading the usable recording-chain performance.

Broadcast Audio Console
The AK5393VS is applicable to broadcast audio conversion paths requiring two high-resolution channels and operation across a broad sampling-rate range. Its 24-bit resolution and 117 dB dynamic range support professional digital audio use, while the serial interface permits connection to downstream digital audio routing or processing. In a console, the converter should follow carefully balanced input stages and maintain a clean separation between analog and digital grounding. Because input voltages above VA+0.3 V or below AGND-0.3 V can damage the converter, source selection, mute behavior, and abnormal-signal conditions must be handled before AIN+ and AIN-.

High-Resolution Studio Capture
For high-resolution studio capture, the AK5393VS provides a 24-bit dual-channel conversion path with 128-times oversampling and operation up to 108 kHz. The 117 dB dynamic range makes it appropriate for capturing signals across a wide amplitude range, provided the microphone preamplifier, converter gain stage, and clock source support the target recording performance. The converter's serial output can feed an FPGA or digital audio processor for storage and routing. Keep analog traces short, place supply-decoupling components close to their pins, and isolate clock and data routing from the input network to preserve signal integrity.

Digital Audio Processing Module
The AK5393VS can serve as the analog-to-digital front end of a modular digital audio processor. Two 24-bit channels are converted at rates spanning 1 kHz to 108 kHz, and the serial interface provides a direct route to digital signal processing or storage logic. The converter must be paired with an appropriate master-clock and interface configuration, so system designers should verify the timing diagrams and mode tables in the manufacturer datasheet. Using local decoupling, short digital routes, and a controlled analog return helps prevent supply and clock disturbances from degrading the 117 dB dynamic-range capability.
Disebarkan
FPGA-Based Audio Capture
The AK5393VS is suitable for an FPGA-based capture architecture where serialized 24-bit converter data is routed into programmable logic for channel processing, filtering, metering, or storage. Its dual-channel format and 1 kHz to 108 kHz sampling-rate range provide flexibility across specialized audio systems. The FPGA interface design should match the converter's serial mode, word framing, and master-clock requirements exactly. Signal-integrity priorities include low-jitter clock distribution, controlled output impedance, uninterrupted reference planes, and separation of high-current digital return paths from the converter's analog input and supply region.
Disebarkan
Multichannel Audio Conversion
Multiple AK5393VS devices can be used to expand a stereo-per-device design into a multichannel professional audio converter, with each device handling two channels. Parallel devices require careful clock distribution so their conversion timing remains coherent, as well as separate analog routing and local decoupling for each converter. The 24-bit resolution and 117 dB dynamic range support high-quality channel capture, while the 108 kHz maximum rate supports high-resolution operation. Before multichannel deployment, verify whether the intended output mode permits synchronized conversion and assess the additional board area, supply loading, and clock distribution requirements.

Catatan Desain
Route AIN+ and AIN- as a compact, matched pair and keep the analog input network away from clock, serial-data, and switching-supply nodes. The AK5393VS operates from +5 V and its analog inputs must remain below the specified upper limit of VA+0.3 V; clamp or attenuate abnormal inputs where necessary. Avoid current above 10 mA into either analog input. High-impedance leakage, unbalanced source impedances, and long parallel stubs can degrade channel matching, so use the manufacturer application circuit as the basis for input conditioning and grounding.
Place supply-decoupling capacitors close to the associated AKM power pins and provide a low-impedance return path beneath the device where the package and layout guidance permit. Separate analog supply distribution from digital and clock-related currents where the board architecture allows it. Do not route high-speed serial signals beneath the analog input region, and minimize vias in sensitive input and ground paths. The +5 V analog supply requirement and the prohibition on overvoltage or excessive input current make protection and local supply implementation central to preventing converter damage.
Do not select a replacement solely because both devices are 24-bit dual-channel ADCs with a 108 kSPS maximum rate. The verified AK5383VS comparison states that some electrical characteristics differ, so review the complete pin table, clock modes, serial interface, full-scale input range, gain behavior, control states, and supply sequencing before changing parts. Confirm that the physical land pattern matches the 28-SOP dimensions and pin numbering. A board-level substitution also requires retesting noise, distortion, synchronization, and downstream data decoding.
Design the clock path around low jitter and keep the master-clock route short and isolated from analog inputs. Validate the supported clock ratio and data-interface mode against the manufacturer timing diagrams for the intended 1 kHz to 108 kHz operating range. Use series damping or source termination only when waveform measurements show ringing, and avoid adding arbitrary components that disrupt the intended clock or data levels. For systems using multiple converters, distribute a coherent clock with matched branch lengths so channel timing remains controlled.
Maklumat Kesediaan
The verified excerpts do not explicitly state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status. AEC-Q100 is not applicable because the AK5393VS is a professional digital audio ADC rather than an automotive-qualified device.
