PCM1601Y - 24-Bit 96kHz 6-Channel Audio DAC | Texas Instruments
MPN： PCM1601Y ✓ 啟用中PCM1601Y 概覽
A multi-channel digital-to-analog converter is an analog-output interface that reconstructs digital PCM audio samples as continuous analog voltage signals. The PCM1601Y belongs to the delta-sigma DAC family, a converter architecture that uses high-frequency oversampling and digital noise shaping to produce a multi-bit analog output from a one-bit internal quantizer. As a six-channel DAC, it can support surround-sound, home-theater, CD-player, DVD-player, and other multichannel audio systems without requiring six separate converter packages.
The PCM1601Y provides 24-bit resolution and supports sampling rates up to 96kHz. Its enhanced multi-level architecture is intended to improve linearity and reduce quantization-related distortion relative to simpler converter implementations. The device also accepts 3V to 3.6V or 5V supply configurations, while the availability of separate analog and digital supply connections helps reduce coupling between digital switching activity and sensitive analog output circuitry. Its 48-MQFP package provides a compact surface-mount solution with 0.8mm terminal pitch.
The converter is designed for audio systems that require six synchronized analog outputs and an I2S-format digital interface. The 96kHz maximum sampling rate supports high-resolution digital audio sources, while 24-bit data resolution preserves a large numerical range for audio processing. Because the output stage still requires appropriate analog filtering and signal-path design, converter resolution alone does not determine final system signal-to-noise ratio or distortion performance. Those results also depend on clocking, grounding, supply implementation, analog output loading, and the selected reconstruction or post-filter network.
Typical PCM1601Y applications include home-theater audio receivers, DVD and CD players, multichannel amplifiers, active speaker electronics, automotive entertainment systems, and professional audio equipment. In each case, the six outputs can serve as the front-left, front-right, center, surround-left, surround-right, and subwoofer channels of a standard surround layout. The converter is particularly useful where multiple digital audio channels must be converted while preserving a common I2S source and sample clock.
System design should give particular attention to analog and digital supply routing. The separate analog and digital supply pins should be connected to appropriately filtered sources, with grounding arranged to minimize return-current coupling from digital signals into the analog output network. Decoupling capacitors should be placed close to the relevant supply pins, and the external clock and I2S data lines should be routed away from sensitive analog outputs. The manufacturer datasheet and pinout must be checked against the exact board revision before finalizing the schematic or PCB layout.
This product record combines distributor specifications, package information, sourcing details, and engineering guidance for the PCM1601Y. It also separates verified PCM1601Y attributes from parameters that require confirmation from the current Texas Instruments datasheet, helping designers evaluate the six-channel DAC without treating incomplete search snippets as complete device specifications.

典型應用
PCM1601Y 適用於 6 應用s: Home-Theater Audio Receiver, CD and DVD Player, Multichannel Active Speaker System, Automotive Entertainment System, Professional Audio Equipment, Digital Audio Interface and Converter Card.
Home-Theater Audio Receiver
The PCM1601Y is appropriate for a home-theater receiver that must convert six synchronized digital audio channels into analog signals. Its verified 24-bit resolution, 96kHz maximum sampling rate, and I2S interface align with multichannel PCM streams used by surround-sound processors, disc players, streaming sources, and set-top boxes. The six outputs can support front-left, front-right, center, surround, and subwoofer channels. System designers should still implement the manufacturer-specified output filters, preserve a low-jitter clock, and separate analog and digital supply return currents to prevent converter or switching noise from reaching the power-amplifier stages.
推薦
CD and DVD Player
PCM1601Y can serve as the digital-to-analog conversion stage in a CD or DVD player when the source controller supplies compatible I2S audio and clock signals. The converter's 24-bit, 96kHz capability provides adequate resolution and sampling bandwidth for high-fidelity playback systems, while six outputs allow implementation of multichannel or multi-zone analog routing. The analog section should use the datasheet-recommended reconstruction network, and the 3.3V or 5V supply flexibility helps align the converter with mixed-signal logic. Decoupling placement and grounding are critical because they directly influence the audible noise floor and distortion.
推薦
Multichannel Active Speaker System
The PCM1601Y is suitable for an active multichannel speaker system receiving digital audio over I2S and driving several power-amplifier channels. Its six-channel architecture reduces the need for multiple DAC packages, while 24-bit resolution and 96kHz sampling support high-resolution source material. The converter's separate analog and digital supply domains allow a careful mixed-signal board implementation. However, channel alignment depends on reliable master-clock and data-slot configuration, and analog output filtering must be designed according to the Texas Instruments application guidance for the selected output mode and load.
推薦
Automotive Entertainment System
PCM1601Y can be evaluated for an automotive entertainment unit that requires several synchronized audio outputs and accepts an I2S source from an audio processor. Its six-channel format supports cabin audio and zone-routing architectures, while 24-bit resolution and 96kHz sampling align with digital media sources. The commercial temperature grade shown in distributor records must be checked against the vehicle's full environmental requirement, and automotive qualification cannot be inferred from the MPN or package. Robust design also requires verified transient protection, clean power regulation, EMI-aware grounding, and confirmation of the complete Texas Instruments datasheet and qualification information.
推薦
Professional Audio Equipment
The PCM1601Y can be used in professional monitoring, recording, or signal-conversion equipment where a common digital source must produce six analog channels. Its 24-bit format and 96kHz sampling ceiling provide useful resolution for high-quality audio paths, and its I2S interface simplifies connection to digital mixers or DSP platforms. The converter does not itself establish the end-to-end performance level: clock jitter, analog filter topology, output loading, grounding, and power-supply noise remain decisive. Designers should verify the exact output mode and application circuit in the current manufacturer documentation before adapting an existing professional-audio board.
推薦
Digital Audio Interface and Converter Card
PCM1601Y is appropriate for a modular digital-audio interface card that accepts I2S and exposes six analog outputs for test equipment or DSP prototyping. The compact 12mm by 12mm 48-MQFP package preserves board area relative to six discrete converters, while separate analog and digital supply pins support deliberate partitioning. A converter card should provide independent local decoupling, controlled clock distribution, analog output filtering, and accessible test points. Engineers should avoid assuming that the 0.8mm-pitch footprint makes the component interchangeable with other 48-pin converters because terminal assignments and internal functions must match exactly.

選型指南
No verified drop-in substitute is identified for PCM1601Y. Consequently, do not select another manufacturer merely because it offers six channels in a 48-pin package. Treat any proposed substitute as a redesign candidate until its complete pinout, clock architecture, analog output mode, supply requirements, and channel mapping have been compared. For an existing PCM1601Y design, retaining the same converter minimizes board changes and preserves the intended analog and digital partitioning. For a new design, verify dynamic range, distortion, jitter sensitivity, output filtering, and thermal behavior from the current Texas Instruments documentation before committing to the device.

設計說明
Use separate analog and digital supply routing for PCM1601Y, and place the required bypass capacitors immediately beside their associated supply and ground pins. Keep digital return currents out of the analog output and reference paths, while using continuous ground-plane treatment under the converter unless the manufacturer application layout specifies otherwise. Exact component values and permitted supply combinations must be taken from the current Texas Instruments datasheet because those details are not present in the verified search excerpts.
Route the I2S data, bit clock, and master-clock nets as short, controlled-impedance digital connections and keep them away from the six analog outputs. Provide a low-jitter clock source and avoid routing these signals over split or heavily loaded analog and digital supply planes. The layout should preserve symmetry among the analog output paths and avoid long copper traces immediately adjacent to the converter where they could increase parasitic coupling.
Do not treat the 24-bit resolution and 96kHz sampling capability as a complete analog-performance specification. Clock jitter, digital supply noise, output filter selection, and load impedance can still degrade channel-to-channel consistency and signal-to-noise performance. Use the manufacturer-recommended reconstruction or post-filter topology, observe the specified output loading, and evaluate idle and full-scale channel outputs for crosstalk and distortion before production release.
A 48-terminal package does not make two multichannel DACs interchangeable. The likely failure mode is assuming that a substitute with the same channel count and package count has matching pins. Before approving a replacement, compare all 48 terminal assignments, I2S and clock roles, analog output topology, voltage tolerances, channel mapping, and exposed thermal or configuration requirements. The supplied cross-reference search did not verify a drop-in PCM1601Y alternative.
