AK5392VS - 24-Bit Stereo Audio ADC | AKM | 28-SOP
MPN： AK5392VS ✓ 啟用中AK5392VS 概覽
An audio ADC is a specialized data-converter IC that transforms left- and right-channel analog audio signals into digital words for processing, storage, transmission, or playback. Within the signal-chain hierarchy, the AK5392VS belongs to the ADC and DAC category, operates as a delta-sigma audio converter, and ultimately provides a digital interface to a digital audio subsystem or audio processor.
The principal functions are 24-bit stereo conversion, 128-times oversampling, and Enhanced Dual Bit architecture. Its two-channel architecture supports professional stereo recording and monitoring, while the serial digital output allows captured audio data to be transferred to an audio codec, DSP, digital mixer, or host processor. The operating range of 1 kHz to 54 kHz makes the converter applicable to multiple professional digital-audio sampling environments.
The AK5392VS uses Enhanced Dual Bit technology within its modulator, an approach associated with improved representation of low-level signals in professional audio conversion. A 24-bit conversion resolution provides a wide digital code range and supports high-fidelity audio processing. Exact signal-to-noise ratio, total harmonic distortion, analog input range, digital interface format, clock requirements, and power-supply limits should be confirmed in the manufacturer datasheet before a circuit is released.
Typical applications include professional digital audio consoles, studio recording equipment, broadcast consoles, digital mixing consoles, high-end audio interfaces, and multichannel monitoring systems. The part is most appropriate when the design requires stereo conversion, 24-bit resolution, and a serial digital audio interface rather than a general-purpose, high-speed multiplexed data converter.
Layout is as important as the converter specifications. Place analog input and clock circuitry away from digital output and switching-regulator areas, follow the manufacturer’s recommended application circuit, and provide stable reference and supply connections. Decoupling, grounding, and controlled clock routing directly help preserve full-scale performance and minimize distortion in a precision audio system.
This page consolidates the AK5392VS format, converter specifications, sourcing guidance, drop-in alternatives, and practical integration notes into one engineering reference. It also separates confirmed product characteristics from parameters that require direct verification against the manufacturer datasheet.

典型應用
AK5392VS 適用於 6 應用s: Professional Digital Audio Console, Studio Recording Interface, Broadcast Audio Console, Digital Mixing Console, High-End Audio Interface, Digital Audio Monitoring System.
Professional Digital Audio Console
The AK5392VS fits stereo conversion stages in professional digital mixing consoles because it combines 24-bit resolution, two channels, and 128-times oversampling in a 28-pin SOP. Place it in the analog input path ahead of a digital mixer or DSP, and route its serial output according to the manufacturer timing diagrams. The 1 kHz to 54 kHz supported sampling range accommodates multiple professional audio rates, while its dedicated stereo architecture avoids using a multiplexed converter for left and right channels. Signal-to-noise ratio, distortion, and jitter limits should be checked against the target console input specification.
推薦
Studio Recording Interface
The AK5392VS is suitable for a studio recording interface that requires dedicated left and right analog-to-digital conversion. Its 24-bit format and Enhanced Dual Bit modulator architecture align with professional audio capture, while the 128-times oversampling ratio supports the converter’s stated operating architecture. The interface designer should implement the manufacturer reference circuit, isolate clock routing from sensitive analog traces, and connect the serial output to the audio DSP or interface controller. Exact input headroom and converter performance should be selected to meet the recording preamplifier and professional mastering requirements.
推薦
Broadcast Audio Console
The AK5392VS can serve as the stereo ADC in a broadcast console input channel when the system operates at supported digital-audio sampling rates. Its two-channel organization maps directly to program and auxiliary or left and right paths, while 24-bit conversion supports downstream headroom for mixing and processing. Use the manufacturer application circuit as the baseline for analog filtering, reference connections, clocking, and decoupling. The implementation must also account for broadcast routing requirements and the converter’s exact dynamic-range specification, which should be confirmed before the board is approved.
推薦
Digital Mixing Console
The AK5392VS supports the stereo analog acquisition requirement of a digital mixing console because it provides 24-bit, two-channel conversion with serial digital output. It can feed channel-level audio data into a mixer DSP after the required clock and data protocol are configured. The converter should be placed close to the analog input conditioning network, with short protected traces and a quiet ground strategy to preserve converter performance. The supported 1 kHz to 54 kHz range makes it applicable to multiple professional sample-rate environments, but clock topology and data-format compatibility must match the selected mixer processor.
推薦
High-End Audio Interface
The AK5392VS is applicable to a high-end stereo audio interface that separates high-resolution conversion from a downstream digital audio engine. Its 24-bit stereo architecture provides the converter foundation for left and right channels, and the 128-times oversampling design is specifically associated with professional digital-audio conversion. The board should implement balanced input conditioning and grounding in accordance with the manufacturer reference circuit, then pass serial data to a codec, DSP, or USB audio controller. Confirm analog range, dynamic range, distortion, and clock-jitter sensitivity against the interface’s published performance target.
推薦
Digital Audio Monitoring System
The AK5392VS can support stereo monitoring and measurement paths where 24-bit digital audio samples are required. Its two-channel structure permits simultaneous left and right acquisition, and the serial output provides a straightforward connection to a monitoring DSP or display processor. Accurate results depend on a low-jitter master clock, reference arrangement, clean analog input path, and ground partitioning that follows the manufacturer layout guidance. Since the available product information does not quantify dynamic range or distortion, the converter should be benchmarked against the monitoring system’s accuracy specification before production release.

設計說明
Separate the analog input path from digital output, clock, and switching-supply regions. Route the converter inputs as short, symmetric traces, use a continuous ground plane, and place analog components close to their associated pins. Follow the manufacturer application circuit for reference and decoupling placement because the converter’s usable audio performance depends on clean input and clock conditions as well as nominal component selection.
Treat the master clock and serial data lines as high-speed signals even though the converter targets audio rates. Use controlled-impedance routing where applicable, minimize stubs, provide clean clock sources, and keep return paths continuous. Jitter and crosstalk can degrade the digital representation before downstream filtering removes them, so verify timing margins against the manufacturer interface diagrams and the host processor requirements.
Implement separate analog and digital supply paths as shown in the manufacturer reference design, including the recommended local bypass capacitors and grounding topology. Confirm the permitted supply voltages, sequencing requirements, and typical or maximum current before selecting regulators. Do not derive power loss or junction temperature without the actual supply voltage, current, and thermal data; those values must come from the device documentation and board environment.
Avoid replacing the manufacturer’s reference, clock, filtering, or grounding arrangement with generic assumptions. A valid audio board also depends on stable sampling clocks, correct master versus system-clock relationships, supported serial data formatting, and compatible logic levels. Review the ordering suffix and device marking carefully when using AK5392VS-E2 as a substitute because suffix-specific conditions have not been fully characterized in the current references.
