AK5720VT - 24-Bit 96kHz Stereo Audio ADC | AKM
N.º de pieza: AK5720VT ✓ ActivoAK5720VT Descripción general
An audio ADC is a mixed-signal data-conversion IC that accepts analog audio voltage signals, samples them at controlled intervals, and converts each sample into a high-resolution digital representation. This function belongs to the broader ADC and DAC hierarchy, which forms part of the converter-IC and signal-processing markets. The AK5720VT is specifically an audio converter rather than a general-purpose instrumentation ADC, so its architecture and interfaces are optimized for digital-audio timing, channel data, and audio signal-chain requirements.
The principal specifications available from the supplied manufacturer and distributor records include 24-bit conversion resolution, 96 kHz sampling capability, two-channel operation, 102 dB dynamic range, I2S digital output, and an integrated input gain amplifier. Its single-ended analog input arrangement can simplify the microphone preamplifier layout. The 16-TSSOP package is also substantially smaller than many older discrete multi-channel audio converter packages, although its exposed lead pitch still requires careful PCB layout.
The AK5720VT supports digital-audio systems operating at up to 24 bits and 96 kHz. Its 102 dB dynamic range is relevant to applications where signal amplitude changes significantly and quiet passages must remain distinguishable from louder program material. The integrated input gain amplifier reduces the need for a separate gain stage when designing compact microphone-oriented front ends, while I2S-compatible output supports connection to digital-audio processors, receivers, transmitters, and interface controllers.
Typical uses include digital recording equipment, microphone preampliers, sound-field acquisition systems, consumer-audio equipment, and industrial monitoring products. In each case, the converter’s role is to transform the analog microphone or line-level signal into digital audio data. System-level signal-to-noise performance still depends on the analog gain structure, power supply quality, clocking, grounding, PCB layout, and the performance of the downstream digital-audio processor.
The primary design consideration is to treat the AK5720VT as a mixed-signal device. Place input and decoupling capacitors close to the appropriate pins, keep analog and digital return-current paths controlled, and use a clean clock source. Because the supplied records do not provide the complete manufacturer pin table, exact electrical limits, power-supply range, or absolute maximum ratings, those items should be confirmed in the manufacturer datasheet before schematic capture.
This page consolidates the verified AKM product description, distributor specifications, sourcing links, interface details, and engineering guidance. It also distinguishes documented AK5720VT characteristics from parameters that require datasheet confirmation, helping engineers evaluate this 24-bit, 96 kHz audio ADC without confusing a similar converter with a verified drop-in replacement.

Aplicaciones típicas
AK5720VT es adecuado para 6 aplicacións: Digital Microphone Preamplifier, Professional Audio Recording, Sound Field Acquisition, Consumer Audio Equipment, Industrial Acoustic Monitoring, Studio Monitoring and Signal Analysis.
Digital Microphone Preamplifier
The AK5720VT fits compact microphone preamplifiers because it combines a 24-bit ADC with an integrated input gain amplifier and single-ended analog inputs. According to the AKM manufacturer description, the gain amplifier makes the part suitable for microphone applications, while the single-ended input reduces the need for external filtering. A 96 kS/s sampling capability provides sufficient digital-audio bandwidth for high-resolution capture. In implementation, the microphone source, input gain setting, clock source, and I2S receiver must be evaluated together. Confirm the permitted input amplitude and gain range in the full datasheet so the active signal remains inside the converter’s linear operating region without relying on assumptions.
Recomendado
Professional Audio Recording
The AK5720VT is appropriate for professional recording front ends that require two-channel, high-resolution audio conversion. Its 24-bit resolution and 96 kS/s maximum sampling rate support detailed digital capture, while 102 dB dynamic range provides useful headroom for recordings with wide level variation. The integrated input gain amplifier can simplify the analog path, and I2S output provides a direct route to a digital audio processor or recorder. For a production design, evaluate microphone transformer or active front-end compatibility, analog grounding, clock jitter, and downstream word-length handling. The converter’s own 102 dB dynamic-range figure does not guarantee that level if the preceding analog stage or power supply contributes additional noise.
Recomendado
Sound Field Acquisition
The AK5720VT can serve in synchronized sound-field acquisition systems requiring two simultaneous audio channels. According to the verified distributor specifications, the device provides 24-bit conversion at rates up to 96 kS/s through an I2S-compatible interface. This combination is useful when acoustic data must be captured with high numerical resolution for playback, analysis, or archival processing. The dual-channel architecture reduces the need for separate converters when two microphones are used. System planning must still cover channel synchronization, LRCK and MCLK relationships, supported master or slave operation, cable or PCB-induced noise, and synchronization with the wider acquisition platform.
Recomendado
Consumer Audio Equipment
The AK5720VT can be used in consumer audio equipment that digitizes analog sound sources before passing I2S data to a processor. Its 24-bit resolution supports high-quality digital representation, and the 96 kS/s rate accommodates high-resolution audio workflows. The integrated input gain amplifier may reduce component count in line-oriented front ends, provided the source level is compatible with the available gain range. Compared with a discrete ADC plus separate amplifier, the integrated approach can simplify layout and preserve the audio signal over a shorter path. Designers should still maintain clean analog and digital supplies, use local high-frequency bypass capacitance, and isolate clocks and switching regulators from the microphone or line input.
Recomendado
Industrial Acoustic Monitoring
The AK5720VT is suitable for industrial acoustic monitoring when designers need high-resolution, dual-channel sampling from microphone or line-level sensors. Its 102 dB dynamic range and 24-bit conversion support acquisition of quieter and louder sound events, while the 96 kS/s limit provides sufficient bandwidth for many vibration and acoustic-monitoring tasks. The integrated gain amplifier and single-ended input can make sensor conditioning more compact. The converter should be placed in a controlled analog section with robust grounding and clean supplies. Before deployment, verify the exact operating-temperature limits, electromagnetic environment, sensor excitation requirements, and whether the enclosure or wiring introduces noise not included in the converter specification.
Recomendado
Studio Monitoring and Signal Analysis
The AK5720VT can be used in monitoring and signal-analysis equipment that captures analog program material for digital processing. The dual-channel format permits simultaneous conversion of stereo sources, while the 24-bit data path preserves more signal detail than a conventional 16-bit interface. I2S output allows the converter to connect to a digital signal processor, test instrument, or analysis controller. Engineers should pay attention to supported clock mode, sampling-rate derivation, data alignment, and the receiving device’s tolerance for jitter. Because the supplied records do not state full timing tables or distortion values, those details should be taken from the manufacturer datasheet before the clock tree and software interface are finalized.

Notas de diseño
Treat the analog inputs and digital outputs as separate return-current paths. Place the AK5720VT input-network components close to the converter, route clock signals away from microphone or line inputs, and avoid running digital traces beneath sensitive analog nodes. The verified package is a 16-pin TSSOP, so lead pitch and exposed solder-joint geometry should be checked against the manufacturer land pattern. Confirm the complete pin table before assigning power, ground, clock, and I2S nets; the supplied excerpts do not provide a complete numbered pinout.
Provide clean analog and digital supply paths and place local bypass capacitance at the device power pins according to the manufacturer application circuit. Switching regulators or digital processors can introduce noise through shared supply impedance even when the AK5720VT specifies a low-voltage architecture. Because the verified excerpts do not state the numerical supply range, current consumption, or permitted sequencing, use the full datasheet for those values. Do not guess rail voltage or decoupling capacitance during schematic capture.
Design the MCLK and LRCK distribution as a controlled clocking subsystem. According to the supplied Mouser datasheet excerpt, reset and power-down release behavior depends on master or slave operation and on the LRCK or MCLK timing sequence. Verify supported operating modes and required relationships before configuring the source and receiver. Keep I2S data routing short, use a continuous ground reference, and account for source-to-sink clock skew to avoid intermittent framing or data-capture errors.
