AK5576EN - 32-Bit 768 kHz 6-Channel Audio ADC | AKM
MPN: AK5576EN ✗ Akhir HidupAK5576EN Ringkasan
An audio ADC is a specialized data-conversion IC that converts six differential analog audio inputs into digital samples. Within the signal chain, it performs the ADC function, sits between analog microphone or line-level circuitry and a digital audio processor, and ultimately feeds an I2S-compatible DSP, receiver, or recording system. The AK5576EN combines a 32-bit conversion format, 768 kHz maximum sampling rate, and differential input architecture to support high-resolution audio capture.
The six differential channels help reduce sensitivity to common-mode noise when balanced analog sources are used. Its 121 dB dynamic range establishes the usable signal range under the manufacturer’s specified test conditions, while 112 dB signal-to-noise-plus-distortion performance is particularly relevant when the ADC output is reproduced through a high-fidelity audio chain. I2S support simplifies connection to common digital audio processors and converters.
The AK5576EN operates from 1.8 V and 5 V supplies and is housed in a compact 64-QFN package with an exposed thermal pad. Its surface-mount construction supports high-density audio equipment, while the exposed pad provides the primary thermal connection to the PCB when heat must be removed. The manufacturer’s datasheet should be used to assign every supply, clock, analog input, and digital output connection.
Typical applications include professional digital mixers, multichannel preamplifiers, studio recorders, high-resolution audio interfaces, broadcast consoles, and premium home-theater processors. Six differential channels suit systems requiring simultaneous conversion of multiple balanced sources without deploying six separate converter packages.
PCB implementation requires careful partitioning of analog inputs, digital interfaces, clock circuitry, supply connections, and the exposed pad. Place decoupling capacitors near their associated supply pins, maintain short return paths beneath analog circuitry, and follow the pin-description table in the manufacturer datasheet when assigning the 64 package connections.
This product page combines the manufacturer-device characteristics with application guidance, pin-assignment cautions, interface requirements, and sourcing information. It also distinguishes the AK5576EN from lower-resolution audio converters by focusing on its six differential channels, 32-bit conversion, 768 kHz sampling capability, and 121 dB dynamic range.

Aplikasi Umum
AK5576EN cocok untuk 6 aplikasis: Professional Digital Audio Interface, Multichannel Studio Preamplifier, Digital Mixing Console, High-Resolution Network Audio Recorder, Broadcast Audio Processing, Premium Home-Theater Processor.
Professional Digital Audio Interface
The AK5576EN fits a professional multichannel interface requiring six balanced analog inputs to be converted into high-resolution digital audio. Its six differential channels reduce the number of separate converter packages, while 32-bit resolution and a maximum sampling rate of 768 kHz support capture formats beyond conventional CD-rate audio. The 121 dB dynamic range and 112 dB signal-to-noise-plus-distortion specifications provide useful margin for studio monitoring. Use I2S output to feed a digital audio DSP, and keep the converter close to the balanced input circuitry to minimize analog interference.

Multichannel Studio Preamplifier
The AK5576EN is appropriate for a studio preamplifier that must capture several balanced microphone or line signals simultaneously. Six differential ADC channels reduce analog routing complexity and provide consistent conversion across the input bank. The 32-bit format preserves high numerical resolution, while the 768 kHz maximum rate supports high-resolution recording workflows. The analog front end should provide low-noise amplification and proper gain staging before the converter. Because performance depends on the complete signal path, use the 121 dB dynamic-range specification as a device characteristic rather than a guarantee of finished-system noise performance.

Digital Mixing Console
A digital mixing console can use the AK5576EN to convert multiple balanced console inputs before level control, routing, and mixing are performed in a digital signal processor. Six differential channels per package support dense mixer channel counts, while the I2S interface provides a conventional digital-audio connection to the processing engine. The 768 kHz rate and 32-bit conversion suit high-resolution processing, and the 121 dB dynamic range helps preserve low-level program material. PCB designers should separate clock and digital return paths from sensitive analog inputs and use the exposed thermal pad as part of the converter’s grounding and thermal strategy.

High-Resolution Network Audio Recorder
The AK5576EN is suitable for a multichannel network or networked recording appliance that accepts balanced analog line sources and converts them for digital transport. Six differential inputs allow compact acquisition of several channels, while 32-bit data and support for rates up to 768 kHz accommodate high-resolution capture workflows. I2S output can feed a digital transport or processor before encoding. The converter should be placed near the input connectors to limit analog trace length, with balanced routing maintained through the board. Supply decoupling, reference grounding, and clock cleanliness remain essential for realizing the specified dynamic range.

Broadcast Audio Processing
The AK5576EN can serve as the input converter in a broadcast processing chain handling several balanced analog sources before encoding or transmission. Its six differential channels provide a practical channel density for program and auxiliary inputs, while the 121 dB dynamic range and 112 dB signal-to-noise-plus-distortion performance support high-quality capture. I2S output allows a digital signal processor to perform routing, mixing, level control, and encoding. The analog section should maintain balanced connections, while clock, digital, and return-current paths should remain separated from the converter inputs to avoid injecting noise into low-level program material.

Premium Home-Theater Processor
The AK5576EN is useful in a premium home-theater processor that accepts balanced analog surround channels and converts them into a digital audio stream. Six differential inputs align with multichannel surround and zone requirements, while 32-bit conversion and rates up to 768 kHz support high-resolution source handling. I2S output can connect to a digital audio processor before DAC conversion and amplification. The converter should be positioned away from high-current amplifier stages, with quiet analog routing and careful power-ground partitioning. The 121 dB dynamic range helps retain quiet effects and dialogue within the complete theater signal chain.

Catatan Desain
Assign the AK5576EN connections directly from the manufacturer pin-description table and package drawing. The 64-QFN footprint is not enough to establish compatibility because analog inputs, clock signals, control functions, supplies, and the exposed pad each require exact placement. Keep the six differential input routes short and symmetrical, and route their ground references away from clock and digital output paths.
Provide separate, well-decoupled 1.8 V and 5 V rails according to the AKM Semiconductor datasheet. Place the required bypass capacitors at the associated device pins with short ground returns, and avoid sharing high-current return paths with the analog input references. Verify startup, supply sequencing, and voltage limits against the manufacturer document before applying power.
Connect the exposed thermal pad to the PCB ground plane using the manufacturer’s recommended land pattern and via arrangement. The pad supports heat transfer and may also form part of the device’s electrical return. Avoid cutting thermal-via paths with unrelated plane splits, and assess converter dissipation under the highest channel count and sampling-rate conditions relevant to the finished equipment.
Do not select a substitute using channel count and resolution alone. A drop-in candidate must match the 64-QFN pinout, exposed-pad arrangement, supply connections, clocking, control pins, and I2S behavior. Review I2S mode, data alignment, master-versus-slave operation, and clock relationships for every proposed second-source device before releasing the PCB.
