PCM1602KY - 24-Bit 6-Channel 192kHz Audio DAC | Texas Instruments
MPN： PCM1602KY ✓ 啟用中PCM1602KY 概覽
An audio digital-to-analog converter is a signal-conversion IC that transforms digital audio samples into analog voltage signals suitable for amplification, mixing, recording, or line-level output. Within the signal-chain hierarchy, the PCM1602KY belongs to the DAC family, then to audio converters, interface ICs, and ultimately the broader semiconductor category. Six-channel integration reduces the number of separate converter packages required in home-theater, professional audio, and multichannel playback equipment.
The converter operates with 24-bit resolution, reaches a maximum sampling rate of 192 kHz, and provides six output channels. Its enhanced multilevel delta-sigma architecture is intended to support high-resolution audio reconstruction while integrating the digital-to-analog function into one package. The 48-LQFP package provides 48 externally accessible terminals and is suitable for conventional multilayer PCB layouts using surface-mount assembly.
Available device information identifies a maximum analog output of 3.41 V, a settling time of 400 microseconds, and an operating temperature range of -25 °C to +85 °C. These ratings define important selection boundaries: the analog output must remain compatible with the downstream amplifier, and the converter should be operated only within its specified temperature range. The 192 kHz capability supports high-resolution source material and professional audio workflows requiring more than the 48 kHz CD base rate.
Typical uses include multichannel home-theater preamplifiers, surround-sound audio receivers, active speaker controllers, digital mixing consoles, professional monitoring equipment, and automotive infotainment systems. The six-channel architecture is especially useful when a system requires synchronized analog outputs from one digital audio source. System integrators must still design the digital interface, analog output filtering, grounding, and output coupling around the converter’s specified operating conditions.
PCB implementation requires careful treatment of analog and digital return paths, short routing for interface signals, and a stable low-noise supply arrangement. Decoupling should be placed close to the corresponding supply pins, while analog output components should avoid sharing high-current return paths with digital switching circuitry. The six-channel structure reduces package count but still requires balanced component placement and symmetrical routing to minimize channel-to-channel differences.
This page consolidates the PCM1602KY’s resolution, channel count, sampling rate, package, operating limits, sourcing path, and application guidance into an engineering-focused reference. It also distinguishes direct ordering variants from true functional alternatives so designers can verify compatibility before committing to a board revision.

典型應用
PCM1602KY 適用於 6 應用s: Home-Theater Audio Receiver, Professional Audio Monitor Controller, Digital Mixing Console, Active Speaker Network, Automotive Infotainment Audio, Studio Recording and Playback System.
Home-Theater Audio Receiver
The PCM1602KY fits a six-channel home-theater receiver that needs simultaneous high-resolution analog outputs for front-left, front-right, center, surround-left, surround-right, and subwoofer or auxiliary channels. Its 24-bit resolution and 192 kHz maximum sampling rate support high-resolution digital sources, while integrating six DAC channels into one 48-LQFP package. Place the converter near the output-stage analog routing and use short, symmetrical paths from each output to its filtering and amplifier interface. Clock and data traces require controlled impedance and return paths, while power and ground connections need local decoupling. The main design tradeoff is that six outputs share one package and supply system, so thermal, grounding, and channel-matching review must cover the complete multichannel output section rather than one channel at a time.

Professional Audio Monitor Controller
PCM1602KY is appropriate for a professional monitor controller requiring six synchronized analog channels for surround monitoring, source-level control, or multiway active-speaker management. The converter’s 24-bit data path and sampling capability up to 192 kHz preserve high-resolution source information, while the 48-pin LQFP allows controlled integration on a multilayer audio board. Keep the digital audio interface and clock source isolated from sensitive output paths, and confirm that the downstream amplifiers accept the converter’s maximum 3.41 V analog output. Design filtering, gain distribution, and channel-balancing networks with matched components to maintain consistent behavior across all six channels. The shared package also makes careful thermal assessment and identical routing geometry important when maintaining low channel-to-channel variation.
推薦
Digital Mixing Console
The six-channel PCM1602KY can serve as the final digital-to-analog stage in a compact digital mixing console when the design requires 24-bit processing depth and operation at sampling rates up to 192 kHz. Six outputs reduce the number of converter packages and associated routing overhead compared with separate discrete DACs. Place the device between the digital mixer engine and the line-level output circuitry, with local supply bypassing and short analog paths leading to the first active stage. Validate clock synchronization, data-line timing, grounding, and output settling across the full gain range before production. The shared converter and supply architecture simplify board area, but thermal gradients or poorly balanced routing can affect channel consistency, so the layout should use repeated output structures and a quiet analog return network.
推薦
Active Speaker Network
PCM1602KY can be used in an active speaker network or multi-zone amplifier design where six digital audio channels must be converted into analog signals for independent power amplifiers. Its 192 kHz capability is useful for lossless high-resolution playback paths, and its 24-bit conversion resolution supports detailed source content. The converter should sit near the amplifier-input routing, with each analog output passed through the intended channel-specific filter or gain network. Decouple the digital and analog supply sections near the IC and route high-current amplifier returns away from the converter’s quiet output reference. Verify the converter’s 400 microsecond settling time against the channel update and switching requirements. When several zones can mute or change source independently, check whether the chosen interface and control arrangement support the required channel-management behavior.

Automotive Infotainment Audio
PCM1602KY is suitable for a multichannel automotive infotainment audio design that must generate six analog outputs from a digital source, subject to the device’s specified -25 °C to +85 °C operating range. Its 24-bit resolution and 192 kHz sampling capability suit high-fidelity source material, while the 48-LQFP package supports automated surface-mount assembly. Vehicle audio systems require careful EMI control, so the digital clock and data interface should remain away from microphone and radio-frequency sections, and the analog outputs should use compact filtering paths. Validate operating temperature, power sequencing, ground offsets, and electromagnetic compatibility at the system level. The component’s package integrates six channels efficiently, but shared supply and ground paths make power-distribution design and channel-to-channel matching central to reliable automotive performance.
推薦
Studio Recording and Playback System
PCM1602KY fits a studio recording or playback system requiring six simultaneous 24-bit analog outputs at rates as high as 192 kHz. The six-channel architecture can support monitor mixes, multiple playback destinations, or a combination of main and auxiliary outputs without requiring six separate converter packages. For low-noise operation, use a quiet analog ground strategy, compact input filters, and decoupled supply connections close to the device. Validate output settling against the 400 microsecond published value and confirm that the downstream circuitry supports the maximum 3.41 V output. Because channel-matching requirements are strict in studio systems, keep channel routing and passive networks geometrically consistent and test every output for gain, phase, and distortion variation under identical signals.

設計說明
Use the PCM1602 datasheet pin-configuration table as the authority for every connection, especially power, ground, clock, serial data, and control pins. Keep the I2S data and clock routes short, provide a continuous return path beneath them, and avoid routing high-current switching signals parallel to the six analog outputs. A grounded plane or carefully partitioned analog region helps reduce coupling between the digital interface and the output stages.
The six analog outputs should remain compact and should not share high-current return paths with amplifiers, relays, motor drivers, or switching regulators. Place the output filtering and first gain stage close to the converter when the architecture permits, and keep their ground current physically separate from digital return currents. This arrangement reduces channel-to-channel interaction and limits the conversion of switching noise into audible or measurement-domain artifacts.
Do not assume that a related PCM1600-family converter is interchangeable solely because it also supports multichannel audio. Before substituting PCM1602KY/2K or PCM1602KY/2KG4, verify the exact orderable part, package drawing, pin table, supply voltages, clock timing, control defaults, and analog output definition. Related parts such as PCM1602A, PCM1608, and PCM1742 can require different layouts and must not be treated as drop-in replacements without that comparison.
Validate the complete digital interface at the highest intended sampling rate of 192 kHz. Check setup and hold timing, clock jitter tolerance, data-line loading, and the relationship among the converter’s master clock, system clock, and sample-rate signals. Test all six outputs with the same waveform to identify gain, phase, settling, and distortion differences before applying channel-specific calibration or routing decisions.
合規資訊
No exact compliance declaration for PCM1602KY was identified. The PCM1602KY/2KG4 ordering suffix suggests a green-material orderable code, but it does not by itself establish the complete RoHS, REACH, lead-free, halogen-free, or conflict-minerals status. Obtain declarations for the exact assembled ordering code before qualification.
