AK4104ET Présentation
A digital audio interface transmitter, or DIT, is an interface IC that accepts digital audio data and converts it into a standardized serial digital-audio stream. In the hierarchy, a DIT is a digital audio transmitter within the broader class of interface ICs and audio codecs. It is commonly used where a converter, processor, or digital audio source must deliver audio through a standardized digital connection.
The AK4104 supports sample-rate operation to 192kHz and 24-bit audio resolution. Its audio serial port supports four formats, allowing the host interface to select an appropriate data arrangement. The verified distributor listing identifies the device as a one-channel digital audio transmitter in a 16-TSSOP package, while the manufacturer datasheet identifies AES3, IEC60958, S/PDIF, and EIAJ CP1201 compatibility.
The 3.3V operating supply is suitable for low-voltage digital audio equipment where the transmitter must operate from a 3.3V rail. Digital audio standards commonly used with this class of device include S/PDIF for consumer equipment and professional digital audio links. Exact input and output logic levels, timing limits, and electrical characteristics should be confirmed in the manufacturer datasheet before final PCB sign-off.
Typical applications include consumer electronics, professional audio equipment, digital mixers, audio conversion systems, home-theater products, and digital audio source or receiver equipment. The AK4104ET is also relevant when an existing design needs a dedicated transmitter rather than a general-purpose codec.
A key design consideration is interface timing and grounding. The host must provide correctly formatted audio data, clocking, and control signals, while the digital output should be routed with controlled impedance and a properly terminated transmission line when required by the selected standard. Verify the exact pinout and recommended external components against the manufacturer datasheet.
This page combines verified manufacturer and distributor information, standards context, pricing availability, and design guidance. It also clearly separates confirmed specifications from parameters that require additional datasheet data rather than presenting unsupported assumptions.

Applications typiques
AK4104ET convient pour 6 applications: S/PDIF Digital Audio Source, Professional Digital Audio Link, Digital Audio Converter Output, Home Theater Digital Audio, Digital Mixer and Signal Processing, Consumer Audio Interface Bridge.
S/PDIF Digital Audio Source
The AK4104ET fits a digital audio source that must transmit standardized S/PDIF data from an audio processor or converter. Its verified 192kHz maximum sample rate and 24-bit resolution provide headroom for high-resolution consumer and semi-professional audio, while the 3.3V supply matches low-voltage digital systems. Configure the supported serial format, provide valid clocking and audio data, and route the digital output according to the selected interface standard.
Recommandé
Professional Digital Audio Link
AK4104ET is applicable to professional digital audio equipment requiring AES3 or IEC60958-compatible transmission. The manufacturer lists these standards alongside S/PDIF and EIAJ CP1201, making the device useful for digital mixers, studio signal paths, and equipment bridges. Designers should verify the exact electrical timing and interface requirements in the manufacturer datasheet, especially when connecting to long or externally terminated digital links.
Recommandé
Digital Audio Converter Output
A converter or signal-chain device can use AK4104ET when it needs a dedicated digital transmitter rather than relying on a general-purpose interface IC. The 3.3V operating supply, one-channel architecture, and support for four audio serial formats allow integration with digital audio processing stages. Confirm the required serial framing, sample-rate support, and output implementation against the source device and the AK4104 datasheet before PCB release.
Recommandé
Home Theater Digital Audio
AK4104ET can support home-theater equipment that distributes digital audio over S/PDIF or related standardized links. Its 192kHz and 24-bit capabilities suit high-resolution source material, while the 3.3V supply is convenient for compact consumer-electronics boards. The transmitter should be configured with the correct audio serial format and interfaced to the source device using the voltage, timing, and grounding conditions specified by the manufacturer.
Recommandé
Digital Mixer and Signal Processing
For digital mixers and audio processors, AK4104ET provides a dedicated digital audio transmission function in a compact 16-pin TSSOP package. The device can encode audio data according to AES3, IEC60958, S/PDIF, and EIAJ CP1201 standards, allowing the system to choose the required digital link. Confirm channel count, clock relationships, serial formatting, and output timing in the datasheet before integrating with a particular mixer architecture.
Recommandé
Consumer Audio Interface Bridge
AK4104ET is suitable for equipment that receives processed digital audio and must pass it to another digital-audio domain. Its one-channel transmitter format and four supported serial formats can simplify interface adaptation when the host already produces compatible digital data. The 3.3V operating requirement should be checked against the bridge board power budget, and the digital output should be routed with appropriate grounding and signal-integrity practices.

- Dedicated digital audio transmitter function (vs General-purpose interface IC)
- High-resolution digital audio support (vs Lower-rate audio transmitter)
- Compact 16-pin TSSOP implementation (vs Larger-package digital audio transmitter)
Notes de conception
Treat the digital audio connection as a clocked interface rather than a general-purpose logic signal. Confirm the selected AK4104 serial format, clock relationship, and allowed timing from the manufacturer datasheet before routing the PCB. Keep the transmitter output path short where practical, provide a continuous ground reference, and use the required termination or coupling arrangement for the destination equipment.
Place the AK4104ET close to the digital audio source and connector or receiver interface to reduce unnecessary trace length and exposure to noise. Follow the package-specific land pattern and pin numbering from the manufacturer documentation. Because the supplied data confirms a 16-pin TSSOP package but does not provide the complete pin table, verify pin assignments before final routing or assembly.
Do not assume that another digital audio transmitter with a similar sample-rate rating is interchangeable. Compatibility depends on package, pinout, supply voltage, supported standards, serial formats, clocking, and output behavior. The verified cross-reference search did not identify a pin-to-pin replacement for AK4104ET, so use the original manufacturer part or validate a candidate against its complete datasheet.
Informations de conformité
The supplied verified data does not state RoHS, REACH, lead-free, halogen-free, conflict-mineral, or AEC-Q100 qualification status. AEC-Q100 is treated as not applicable because the part is an audio interface IC rather than an automotive-qualified device.
