AK5384VF - 24-Bit 4-Channel 96 kHz ADC | AKM
MPN: AK5384VF ✓ نشطAK5384VF نظرة عامة
An audio ADC is a data-converter IC that converts four analog audio inputs into high-resolution digital samples. Its role within a signal chain is to establish the digital representation used by processors, mixers, storage systems, and communications equipment. The AK5384VF belongs to the ADC and DAC family within integrated circuits and ultimately to the broader semiconductor and signal-conversion hierarchy.
The AK5384VF provides four conversion channels, 24-bit resolution, and an 8 kHz-to-96 kHz sampling-rate range. Its Enhanced dual-bit delta-sigma technique supports high accuracy while targeting cost-sensitive multichannel audio designs. Master-mode operation and TDM output allow the converter to work within synchronized multichannel audio architectures rather than serving as an isolated single-channel codec.
Digital interface features support integration into professional audio, consumer audio, and communications equipment. TDM format is particularly useful when several audio channels must share a digital transport, while master mode provides a defined timing relationship between the converter and the surrounding system. The manufacturer datasheet also documents power-down control and digital-filter reset behavior, including the requirement to reset the filter after power-up.
Typical applications include multichannel digital mixing consoles, surround-sound audio interfaces, broadcast equipment, sound-card front ends, active speaker systems, and industrial audio acquisition platforms. Its four-channel architecture reduces the number of separate converters required in a balanced audio subsystem and provides a common digital interface for channel-rich products.
PCB implementation requires careful analog-input routing, stable supply and ground distribution, appropriate input filtering, and compliance with the manufacturer’s reference layout and decoupling guidance. The analog and digital sections should be positioned to minimize coupling from switching nodes and high-current return paths. Designers should also confirm the exact clock mode and interface timing against the datasheet before releasing a layout.
This product summary consolidates the AK5384VF architecture, sampling capabilities, package information, application guidance, design cautions, and verified sourcing references into one engineering-focused resource. It also identifies the limitations of unqualified replacement candidates so that a proposed substitute is validated for footprint, pinout, interface timing, clocking, and power sequencing before design use.

التطبيقات النموذجية
AK5384VF مناسب لـ 6 التطبيقs: Multichannel Digital Audio Mixer, Surround-Sound Audio Interface, Professional Broadcast Audio Acquisition, Digital Recording Sound Card, Active Speaker System, Industrial Audio Sensor Interface.
Multichannel Digital Audio Mixer
The AK5384VF suits a digital mixer requiring four synchronized analog-to-digital channels at sampling rates from 8 kHz to 96 kHz. Its 24-bit conversion, master-mode operation, and TDM format reduce the number of separate converters and create a consistent path into a mixing DSP. The system clock, TDM slot timing, and channel latency must be configured together so that the converter and processor exchange valid data without conflicts.
موصى به
Surround-Sound Audio Interface
A surround-sound interface can use the AK5384VF to acquire four balanced or unbalanced audio channels through a shared digital transport. The converter’s 24-bit resolution supports detailed digital capture, while TDM output helps conserve connections between the converter and a digital audio processor. Board designers should preserve channel symmetry, use suitable analog filtering, and isolate converter clock and digital return paths from noisy switching circuitry.
موصى به
Professional Broadcast Audio Acquisition
The AK5384VF can support multichannel acquisition stages in broadcast consoles, monitor systems, and production equipment where several audio feeds must be sampled consistently. Its sampling-rate range covers voice through high-resolution program audio, and TDM provides an efficient interface for digital routing. A production design must validate clock jitter margin, channel mapping, power-up reset behavior, and the analog front-end requirements for each input.
موصى به
Digital Recording Sound Card
For a multichannel recording sound card, the AK5384VF provides four 24-bit channels and a TDM path to the host processor. The 8 kHz-to-96 kHz range supports communication capture, multimedia production, and high-resolution monitoring applications. Firmware must establish the master clock and TDM framing correctly, while the analog layout should minimize crosstalk and maintain matched input paths across the four channels.
موصى به
Active Speaker System
An active speaker controller can use the AK5384VF when it must monitor or process several analog audio channels at different operating rates. The four-channel architecture supports multiway monitoring, zone feedback, or auxiliary audio paths, while TDM supports centralized digital routing. The implementation should use the PDN-controlled shutdown sequence correctly and verify thermal behavior and signal integrity over the complete speaker operating range.
موصى به
Industrial Audio Sensor Interface
The AK5384VF can capture multiple audio-derived sensor channels in industrial monitoring equipment where vibration, machinery, or acoustic events must be digitized. Four channels and sampling rates up to 96 kHz permit more detailed waveform analysis than low-rate voice conversion. Because industrial environments may contain strong electromagnetic interference, the design should use controlled grounding, filtering, clock distribution, and shielding or enclosure practices appropriate to the installation.

ملاحظات التصميم
Follow the manufacturer’s recommended analog and digital layout exactly, particularly the placement of input components, decoupling capacitors, clock circuitry, and the exposed routing around the TSSOP-28 leads. Keep high-speed digital clock and data traces away from the four analog inputs. A solid ground plane with a disciplined analog and digital return strategy helps reduce coupling into the delta-sigma modulator.
Drive the PDN pin low to place the AK5384VF in power-down mode and reset its digital filter, then perform the documented reset again after power-up. Avoid starting the host audio engine before converter initialization is complete. Also verify the master clock and TDM slot mapping against the receiving processor; incorrect framing can produce apparently valid but channel-misaligned data.
Use a low-jitter master clock and route it as a controlled clock signal rather than deriving it from an unsuitable digital bus. Provide local supply decoupling at the converter pins and keep the analog-input return path continuous beneath or adjacent to the relevant circuitry. For high-sensitivity inputs, use the manufacturer’s recommended anti-alias network and matched source impedances to avoid channel-dependent amplitude or phase errors.
Keep switching regulators, high-current digital devices, and their return paths away from the analog input section. Use the shortest practical clock connection, maintain a continuous reference plane, and place filtering close to the input pins. If the converter sits beside a switching power stage, inspect the board with an oscilloscope for clock spurs and conducted noise that could otherwise appear as in-band artifacts or channel-to-channel crosstalk.
