PCM1608Y 8-Channel 24-Bit 192kHz Audio DAC | Texas Instruments
MPN： PCM1608Y ✓ 啟用中PCM1608Y 概覽
An audio DAC is a signal-conversion integrated circuit that reconstructs analog waveforms from sampled digital audio data. The PCM1608 belongs to the delta-sigma DAC hierarchy within digital-to-analog converters, ADC/DAC components, and broader data-converter semiconductors. Eight integrated converter channels allow a single device to drive multiple analog audio outputs while accepting digital audio streams from an audio processor, decoder, receiver, or playback system.
The primary features of PCM1608Y are its eight DAC channels, 24-bit conversion resolution, and 192 kHz maximum sampling rate. Its digital interface supports I2S as identified by distributor product data, while the manufacturer describes support for both PCM audio data and DSD audio data. The 48-LQFP (7x7) package consolidates eight converter channels and associated support circuitry into a surface-mount footprint suitable for multichannel consumer and professional audio equipment.
The PCM1608 uses delta-sigma conversion according to the manufacturer datasheet listing. This architecture is relevant to audio because it supports high-resolution digital audio while presenting the external circuit with a single integrated converter package. The verified product data identifies the PCM1608Y dynamic range as 100 dB typical, whereas the related PCM1608 family listing also references a 105 dB typical value; these figures should not be interchanged without checking the specific ordering variant.
Typical applications include surround-sound decoding, multichannel home-theater playback, active loudspeaker systems, digital mixing consoles, professional audio interfaces, and consumer receivers. In these systems, the PCM1608 can convert decoded I2S audio into eight analog output channels. System-level performance still depends on the analog reconstruction network, clock source, digital interface implementation, output loading, grounding, and power-supply quality.
Layout should preserve short digital and analog signal paths, maintain a clean analog ground reference, and place required bypass and reconstruction components close to the device. The verified data does not disclose the complete pin assignment or component values, so engineers should use the current Texas Instruments datasheet and associated application information before finalizing PCB routing, decoupling, or analog output stages.
This product page combines verified manufacturer and distributor information, current as of 2026-10-30, with explicit data gaps, sourcing guidance, and practical selection criteria. It distinguishes confirmed PCM1608Y characteristics from unverified family-level or competitor information so engineers can make sourcing and design decisions without relying on unsupported specification assumptions.

典型應用
PCM1608Y 適用於 6 應用s: Surround-Sound Home Theater, Multichannel Active Loudspeakers, Professional Audio Interface, Digital Audio Mixer and Console, AV Receiver and Network Player, Digital Audio Converter.
Surround-Sound Home Theater
The Texas Instruments PCM1608Y fits multichannel home-theater playback because it combines eight DAC channels, 24-bit resolution, operation up to 192 kHz, and I2S connectivity in one 48-LQFP device. A surround-sound processor can supply synchronized digital audio channels to the converter, which produces eight analog outputs for amplifiers and powered speakers. The verified PCM1608Y dynamic range is 100 dB typical, providing a defined performance target for the analog playback path. Digital-interface timing, channel assignment, output filtering, and grounding must follow the current TI datasheet, because the supplied source excerpts do not provide the complete pinout, clock requirements, or analog output topology.
推薦
Multichannel Active Loudspeakers
PCM1608Y is applicable to powered or active loudspeaker platforms that require multiple synchronized analog outputs from a common digital source. Its eight integrated DAC channels can reduce the number of separate converter packages when the amplifier board accepts eight balanced or unbalanced analog channels. The device supports 24-bit PCM, DSD, and I2S audio data, allowing it to sit downstream of a decoder or network audio processor operating up to 192 kHz. Actual deployment depends on the confirmed output configuration, supported clocking, bypass requirements, and analog reconstruction network, all of which must be checked in the manufacturer documentation before PCB release.
推薦
Professional Audio Interface
The PCM1608Y can serve as the multichannel output stage of a professional audio interface that accepts digital audio from a converter, DSP, or computer interface. Eight 24-bit channels and support for sampling rates up to 192 kHz are useful for multichannel monitoring, recording, and digital mixing systems. Its 100 dB typical dynamic range for PCM1608Y provides a clear basis for selecting matching converter, gain, and output stages. Designers should treat the DAC as only one element of the signal chain and verify clock ratios, input latency, analog output mode, channel mapping, and reconstruction-filter requirements against the official Texas Instruments PCM1608 documentation.
推薦
Digital Audio Mixer and Console
PCM1608Y is suitable for digital mixers and consoles requiring multiple high-resolution analog playback outputs. A mixer DSP can send eight channels over the supported digital interface, and the PCM1608Y converts those streams at up to 192 kHz with 24-bit resolution. This arrangement can centralize conversion for powered monitor outputs, zone amplifiers, or line-level destinations while retaining one converter package. In a console, low-noise analog design, independent channel routing, mute behavior, and isolation from digital return noise are critical. The verified information does not include mute, gain-control, or output-stage functions, so those capabilities must not be assumed; consult the complete datasheet and application circuit.
推薦
AV Receiver and Network Player
The eight-channel architecture of PCM1608Y aligns with audio output sections in AV receivers, media players, and network audio systems where multiple decoded channels feed separate amplifiers. Its support for I2S, PCM, and DSD audio data allows it to accept digital streams generated by a host decoder, provided the required formats and clocks are supported by that source. With operation up to 192 kHz and 24-bit conversion resolution, the device is relevant to high-resolution consumer-audio designs. Implementation must account for channel assignment, mute and standby requirements, analog ground isolation, output filtering, and thermal management of the surrounding receiver enclosure.
推薦
Digital Audio Converter
PCM1608Y can act as the central eight-channel DAC in a standalone digital-to-analog converter for home or studio use. A USB, network, or optical digital source can feed supported PCM, DSD, or I2S audio into the device, which supplies eight analog outputs for external amplifiers. The converter's 192 kHz maximum rate and 100 dB typical dynamic range for PCM1608Y are useful when designing high-resolution multichannel playback equipment. The actual achievable performance also depends on the source interface, clock architecture, analog reconstruction network, output topology, and power supply. The complete TI pinout and electrical data are required before finalizing routing and component selection.

主要差異化特點
- Eight DAC channels integrated in one converter (對比PCM1604)

- Lower listed unit price for the base ordering option (對比PCM1608Y/2K)
設計說明
Keep the digital audio, clock, and analog output paths short and physically separated where practical. Place required bypass capacitors adjacent to their supply pins, use a low-impedance ground reference for the converter, and avoid routing digital return currents beneath sensitive analog outputs. The supplied excerpts do not include the official land pattern or pin map, so PCB implementation must be checked against the current Texas Instruments PCM1608 datasheet before fabrication.
Design the analog and digital supplies around the exact voltage, current, sequencing, and decoupling requirements stated in the manufacturer datasheet. Those limits are not present in the supplied excerpts and are therefore not guessed here. Because PCM1608Y supports PCM, DSD, and I2S data, verify that the source, clock generator, and converter can share a stable reference without introducing excessive jitter or incompatible clock ratios.
Treat I2S data, bit clock, and system clock as a tightly related digital interface. Use source-terminated or series-damped clock routing where edge rates demand it, maintain continuous reference planes, and confirm setup and hold timing at the PCM1608Y pins using the official timing data. The 192 kHz sample-rate capability does not by itself guarantee robust operation if the source clock and data lines are poorly implemented.
Do not select PCM1608Y solely from channel count and sample rate. Confirm output topology, analog full-scale range, supported clocking, data format, latency, power rails, and package details in the current manufacturer documentation. Likewise, do not approve a substitution solely because a distributor labels it an equivalent; the verified cross-reference evidence supports package and terminal consistency for the listed same-brand candidates, not every function of an unspecified competitor.
合規資訊
The supplied excerpts do not contain explicit RoHS, REACH, lead-free, halogen-free, conflict-minerals, or automotive-qualification statements. No compliance claim has been inferred from the ordering suffix or distributor category.
