PCM1608KY - 8-Channel 24-Bit 192kHz DAC | Texas Instruments
MPN: PCM1608KY ✓ NakahandaPCM1608KY Ulas
An audio DAC is a power-management and signal-conversion semiconductor that converts digital audio samples into continuous analog voltage signals. In the broader hierarchy, PCM1608KY belongs to the digital-to-analog converter family, then to audio converter ICs, interface and signal-conversion ICs, and finally the broader semiconductor category. It is commonly positioned after a digital audio processor, where parallel or serial digital audio data is converted into eight analog output channels for amplification, recording, mixing, or powered speakers.
The principal specifications are an eight-channel DAC configuration, 24-bit audio resolution, a 192kHz maximum sampling rate, and an I2S-compatible interface. The monolithic CMOS implementation consolidates eight converters and their associated support circuitry into one package. This channel count makes the device useful in multichannel audio systems where replicating eight separate high-resolution DAC channels would otherwise increase board area, routing complexity, and assembly cost.
The enhanced multilevel delta-sigma architecture uses fourth-order noise shaping and 8-level amplitude quantization. Noise shaping moves quantization noise away from the most perceptually important portion of the audio band, while multilevel quantization helps improve tolerance to clock jitter and reduces sensitivity to input timing variation. The device supports both PCM audio data and Direct Stream Digital audio data formats, giving designers flexibility when connecting digital sources, AV receivers, music servers, or networked audio platforms.
Typical applications include home-theater audio, multichannel soundbars, professional audio mixers, digital recording equipment, active speakers, and automotive or embedded audio systems. The 48-LQFP package provides a conventional surface-mount assembly format, while its exposed thermal-pad construction supports heat transfer through the PCB when multiple channels operate continuously at high sample rates.
PCB design should preserve short, impedance-controlled connections among the digital interface, clocking circuitry, analog outputs, and decoupling network. Place input and output capacitors at their associated pins, route analog outputs away from switching nodes, and use a solid ground-plane strategy to reduce channel-to-channel crosstalk. Confirm analog output loading, supported master-clock arrangements, and output-filter values against the manufacturer datasheet before finalizing the board.
This product record combines the manufacturer architecture description, package and sampling-rate details, verified distributor listings, practical application guidance, and a clearly constrained replacement assessment. That combination helps engineers evaluate the PCM1608KY for multichannel audio designs while distinguishing verified pin-compatible alternatives from parts that merely perform a similar conversion function.

Tipikal na mga Gamit
PCM1608KY ay nararapat para sa 6 aplikasyons: Home-Theater Audio Receiver, Multichannel Soundbar, Professional Audio Mixer, Digital Recording Equipment, Active Speaker Network, Networked Music Player.
Home-Theater Audio Receiver
The PCM1608KY fits a home-theater receiver requiring eight synchronized high-resolution analog outputs from one digital audio transport. Its eight 24-bit DAC channels, 192kHz maximum sampling rate, and PCM or DSD support align with surround-sound and music-source architectures while reducing the number of separate converter packages. The 48-LQFP device also provides a clear path from digital processing to line-level analog outputs. Design attention should remain on clock routing, synchronized channel behavior, output filtering, and separating sensitive analog paths from switching circuitry.
Inirekomenda
Multichannel Soundbar
A soundbar can use the PCM1608KY to reconstruct several surround or music channels from a digital audio stream. The converter's eight-channel organization limits the number of external DAC packages, while 24-bit resolution and support for rates up to 192kHz suit high-fidelity playback. Because the package is a 7mm by 7mm LQFP, board planning must account for its lead pitch, exposed thermal pad, analog routing, and nearby output-stage components. The clock and data interface should also be placed away from display and switching-power circuitry.
Inirekomenda
Professional Audio Mixer
The PCM1608KY suits a digital mixer or rack processor that requires multiple high-resolution outputs for monitoring, auxiliary buses, or recording channels. Eight integrated 24-bit DAC channels can simplify the converter section while supporting sampling rates up to 192kHz for high-resolution workflows. Designers should verify each output's loading, scaling requirements, and termination method in the datasheet. Ground-plane zoning and symmetric analog routing are important because multichannel circuitry magnifies the effect of shared impedance and digital coupling.
Inirekomenda
Digital Recording Equipment
For multichannel digital recorders and studio monitor controllers, the PCM1608KY can convert incoming PCM audio into eight analog outputs without using eight discrete converter packages. Its 24-bit word length and 192kHz capability support high-resolution capture workflows, while the monolithic CMOS implementation helps control channel-to-channel variation. The design should account for converter latency, synchronization with recording circuitry, output reference behavior, and grounding of the analog section. Decoupling and reconstruction-filter layouts should follow the manufacturer application guidance.
Inirekomenda
Active Speaker Network
The PCM1608KY is appropriate for an active-speaker or distributed-audio controller that converts digital program material into several analog channels before power amplification. Centralizing eight 24-bit DAC channels in one 48-LQFP package simplifies multichannel routing and can preserve uniform digital audio handling. The practical trade-off is the converter's thermal and layout requirements: all channels must operate within the package limits, and analog outputs should be routed away from processor and switching-supply nodes. Output filtering and amplifier-input scaling must also be selected for the intended speaker drive.
Inirekomenda
Networked Music Player
A high-resolution networked music player can use the PCM1608KY to provide multiple analog outputs from a digital audio processor. Support for PCM and Direct Stream Digital audio data allows the converter to support conventional and DSD sources, provided the upstream source and interface satisfy the device requirements. Eight 24-bit channels benefit users of multichannel or multi-zone audio equipment, while 192kHz operation addresses high-resolution source formats. The digital clock and serial-data paths require short, controlled routing, and the analog outputs should receive dedicated filtering.

Talaan ng Disenyo
Assign the 48-LQFP land pattern directly from the manufacturer package drawing and confirm pin-1 orientation before routing. Place the digital interface, supply bypass capacitors, and decoupling components close to their associated pins. Keep analog outputs short and avoid sharing narrow return paths with clock, serial-data, or power-converter traces. Use a continuous ground reference beneath the device while separating noisy switching-current paths from the analog output region.
Treat clock, serial-data, and clock-domain signals as controlled-impedance digital connections even though the interface is associated with an audio converter. Match the supported clock architecture, route the clock away from analog outputs, and avoid unnecessary stubs or test-point branches. Confirm setup and hold requirements, supported sampling rates, and synchronization behavior in the manufacturer datasheet so that data timing remains reliable at 192kHz.
Eight DAC channels operating continuously can generate more heat than a single-channel converter, so thermal verification should include the complete 48-LQFP footprint and exposed-pad design. Provide the manufacturer-recommended land pattern, adequate via density, and uninterrupted copper where permitted. Use an estimated junction-temperature calculation based on actual dissipation, ambient temperature, and the board's thermal resistance, then confirm the result against the device's maximum operating temperature.
Do not treat PCM1608KY and PCM1608KY/2K as interchangeable without checking their complete ordering attributes. Likewise, PCM1609APT is not a confirmed drop-in substitute merely because it is associated with a similar PCM160x family. Verify package dimensions, exposed-pad requirements, every pin assignment, analog output configuration, clock requirements, format support, and thermal limits before releasing a replacement or second-source BOM.
