AK5383VS - 24-Bit 96kHz Stereo Audio ADC | AKM
MPN： AK5383VS ✓ 啟用中AK5383VS 概覽
An audio ADC is a specialized data-converter IC that transforms balanced or unbalanced analog audio into digital PCM data. The digital-audio ADC category sits within signal-chain and data-converter ICs, where precision, low distortion, clocking, and output-interface compatibility determine whether the converter is suitable for recording equipment, digital mixing consoles, studio monitors, broadcast infrastructure, or professional audio interfaces.
Key features include 24-bit conversion resolution, two simultaneous analog channels, 128-times oversampling, and a maximum sampling rate of 96 kHz. According to the AKM datasheet, the Enhanced Dual Bit architecture provides 110 dB dynamic range while retaining the low-distortion characteristics associated with single-bit delta-sigma modulators. These characteristics make the AK5383VS appropriate for professional conversion stages requiring high-resolution audio capture.
The converter integrates a two-channel audio ADC and a configurable digital audio output stage. Its serial interface supports integration with digital audio processors, clock controllers, sample-rate converters, and professional digital consoles. Designers should treat the analog input, reference, power, ground, and digital clock connections as separate implementation domains because correct partitioning directly affects noise, channel matching, and signal integrity.
Typical applications include professional audio interfaces, digital mixing consoles, studio recording equipment, broadcast monitoring, digital loudspeaker processors, and multichannel measurement systems. The two-channel architecture is particularly useful where stereo or balanced dual-channel conversion is required without implementing two separate single-channel converter packages.
The primary design consideration is preserving the quality of the analog front end. Balanced inputs, low-noise protection resistors, suitable anti-alias filtering, solid grounding, and clean clock distribution can be as important as the nominal ADC resolution. The +5 V supply and analog inputs also require attention to the datasheet limits because excessive input voltage or current can damage the converter.
This product overview combines the manufacturer’s converter architecture, channel and sampling-rate details, package information, application guidance, and drop-in comparison considerations into one engineering reference. It is intended to help hardware designers evaluate signal-chain fit, interface compatibility, and board-level implementation before committing to a professional audio design.

典型應用
AK5383VS 適用於 6 應用s: Professional Stereo Audio Interface, Digital Mixing Console, Studio Recording and Monitoring System, Broadcast Monitoring System, Digital Loudspeaker Processor, Multichannel Audio Measurement.
Professional Stereo Audio Interface
The AK5383VS fits professional stereo and dual-channel interface front ends because it combines two analog channels with 24-bit resolution and a maximum sampling rate of 96 kHz. Its 128-times oversampling and 110 dB dynamic range provide a suitable conversion core for capturing balanced studio signals without using separate converter packages for each channel. Place the device behind a balanced input buffer and anti-alias network, then route its clock and serial data to the interface controller. The +5 V analog supply and AGND reference must remain clean because supply noise or ground-current coupling can degrade the converter’s effective noise floor.
推薦
Digital Mixing Console
The AK5383VS can serve as the dual-channel conversion element at the input boundary of a professional digital mixing console. Two channels at 24-bit resolution and up to 96 kHz suit high-resolution studio and live-sound workflows, while the 110 dB dynamic range supports professional signal headroom. The converter should receive a stable reference clock and isolated routing toward the console’s digital processing fabric. Local input filtering and balanced buffering are essential for controlling aliasing and preserving channel matching. Clock jitter, return paths, and the separation between analog and digital return paths require deliberate PCB planning.
推薦
Studio Recording and Monitoring System
For studio recording, monitoring, and return-path conversion, the AK5383VS provides a two-channel, 24-bit ADC with 96 kHz sampling capability. Its Enhanced Dual Bit delta-sigma architecture and 110 dB dynamic range align with professional audio acquisition rather than general-purpose measurement conversion. The device can capture a balanced stereo or dual-channel input, provided the analog stage respects the stated VA+ + 0.3 V and AGND - 0.3 V input limits. Decoupling capacitors, a low-noise reference arrangement, and short return paths should be placed according to the manufacturer application guidance. Digital outputs then feed the recorder, DSP, or clock-routing circuitry.
推薦
Broadcast Monitoring System
The AK5383VS is suitable for broadcast monitoring, program-quality return channels, and professional audio measurement paths requiring two simultaneous inputs. Its 24-bit format and 96 kHz maximum rate provide a practical conversion resolution for studio, post-production, and transmission monitoring environments. The two-channel structure reduces component count when monitoring a stereo pair or two related balanced sources. Keep the converter’s analog section physically separated from switching regulators and digital clocks, and route the digital outputs to the monitoring processor through controlled impedance paths. Input protection must preserve the converter’s absolute current and voltage limits without clipping normal program levels.
推薦
Digital Loudspeaker Processor
The AK5383VS can provide the analog-to-digital front end for a professional digital loudspeaker processor that accepts balanced stereo or dual-channel program audio. Twenty-four-bit conversion, 96 kHz sampling, and 110 dB dynamic range are useful when preserving low-level program detail before crossover, limiting, and delay processing. A low-noise input buffer and correctly scaled balanced network should precede the ADC, while the converter clock must remain synchronized with the processor’s digital audio engine. Separate analog and digital ground-return paths help prevent processor switching activity from appearing as channel noise. The system designer should also verify allowed input amplitude and current before adding external protection.
推薦
Multichannel Audio Measurement
The AK5383VS is appropriate for synchronized dual-channel measurements where a professional audio converter is preferable to a general-purpose ADC. Its two-channel structure enables comparative capture of two balanced signals, while 24-bit resolution and 128-times oversampling preserve low-level detail. Both channels share the converter environment, so careful symmetry in the input buffers helps maintain channel consistency. Use stable low-jitter clocks and verify synchronization behavior against the measurement controller. The +5 V supply network should be filtered for the analog section, and signal amplitudes must remain within the documented absolute input limits to prevent damage or nonlinear behavior.

設計說明
Partition the analog input, converter, clock, and digital-output regions so that high-current supply and clock returns do not share narrow paths with AIN+, AIN−, or AGND. Place input protection and filtering close to the source connector, then connect balanced signals to the converter through a symmetrical low-noise network. Keep digital-output routing away from the analog inputs. This arrangement reduces ground coupling and helps preserve the converter’s 110 dB dynamic-range capability.
Normal analog signals must remain within the AKM datasheet’s absolute input limits of AGND - 0.3 V to VA+ + 0.3 V, and current into the analog input pins must not exceed 10 mA. Do not interpret these values as the recommended signal range. Use balanced attenuation, impedance conversion, and clamp protection to handle connector faults and hot-plug events. Excessive input voltage or current can damage the AK5383VS even when normal program audio appears correctly scaled.
Treat the AK5383VS system clock and serial outputs as high-speed digital signals even though the converter targets audio. Route clocks over continuous reference planes, use appropriate source termination where recommended by the associated digital interface, and avoid stubs. Keep clock jitter and crosstalk away from the analog section. Because the AK5383VS supports 96 kHz conversion, a clean clock is essential for preserving the timing margin and low-noise performance expected in professional audio equipment.
Provide a quiet +5 V supply to the analog section and decouple the converter at its supply pins with the capacitance and placement specified by the manufacturer’s application guidance. Keep switching-regulator outputs and their high-current return paths away from AGND. Starve or carefully isolate sensitive return currents rather than creating a broad loop between analog and digital ground. A stable reference and low-impedance supply return are essential for achieving repeatable professional-audio performance.
合規資訊
The AK5383VS is an integrated-circuit product for professional digital audio rather than an automotive-qualified component. RoHS, REACH, lead-free, halogen-free, and conflict-minerals status require confirmation from the current manufacturer environmental declaration.
