PCM1602Y - 24-Bit 192kHz 6-Channel DAC | Texas Instruments
MPN: PCM1602Y ✓ Hoạt độngPCM1602Y Tóm tắt
A DAC is a digital-to-analog converter, a signal-conversion IC that transforms sampled digital audio into corresponding analog voltage signals. The PCM1602Y belongs to the broader hierarchy of DAC, audio converter, signal-conversion IC, and semiconductor. Its six-channel architecture reduces the number of separate converters required when reproducing multichannel sound, while the I2S interface supports integration with digital audio processors, receivers, and consumer-audio equipment.
Principal features include 24-bit resolution, a maximum sampling rate of 192kHz, and six-channel conversion. The I2S interface provides a conventional digital-audio connection to the surrounding system. The device also uses an enhanced multilevel delta-sigma conversion architecture, combining high-resolution digital-to-analog conversion with an integrated audio-converter format suitable for consumer and professional equipment. Its 48-LQFP package measures 7x7mm.
The PCM1602Y supports separate analog and digital supply sources, allowing analog and digital sections to be connected to suitable supply rails. A documented alternative-source description states supply ranges of 3V to 3.6V and 5V, although exact rail assignments and detailed operating limits should be confirmed in the manufacturer datasheet. Because the converter handles six channels, careful treatment of digital clocking, analog output filtering, grounding, and supply decoupling is essential to preserve audio quality.
Typical uses include multichannel home-theater audio, powered speakers, AV receivers, digital active speakers, automotive audio systems, and professional playback equipment. The 192kHz sampling capability makes the device appropriate for high-resolution source material, while the six-channel output count suits surround-sound and multi-zone audio architectures. System designers must still ensure that the host processor supplies valid I2S data, required timing, and an appropriate master-clock relationship.
For implementation, place decoupling capacitors close to the supply pins and keep the digital interface traces away from sensitive analog output paths. Confirm the manufacturer's recommended analog-output topology and external component values before production. Also verify the exposed-pad, thermal, and PCB-layout requirements associated with the 48-LQFP package rather than relying only on generic package guidance.
This page consolidates the verified 24-bit, 192kHz, six-channel, I2S, and 48-LQFP characteristics with distributor pricing, a verified same-package alternative, comparison guidance, and practical integration considerations. It is intended to help engineers evaluate sourcing and design fit while clearly identifying details that still require confirmation from the official datasheet.

Ứng dụng tiêu biểu
PCM1602Y phù hợp cho 6 Áp dụngs: Multichannel Home-Theater Audio, Powered Speaker and Soundbar, Automotive Audio Head Unit, Professional Audio Playback, Digital Audio Interface and Recorder, Multi-Zone Audio Distribution.
Multichannel Home-Theater Audio
The PCM1602Y fits a home-theater audio output stage because it combines six DAC channels, 24-bit resolution, and sampling up to 192kHz in one 48-LQFP device. A surround-sound receiver can use its six-channel output rather than requiring six separate stereo converters. The I2S interface can connect to a digital audio processor carrying the decoded channel stream. Designers must still verify supported channel mapping, required master-clock ratios, and the recommended analog reconstruction network. Proper separation between digital and analog grounding is important at 192kHz so switching activity and clock edges do not degrade the reconstructed outputs.

Powered Speaker and Soundbar
A powered speaker or soundbar can use the PCM1602Y when the product requires multiple high-resolution audio outputs in a compact controller. Its six-channel configuration supports main left and right channels plus additional surround or zone channels, while the 24-bit/192kHz conversion preserves high-rate digital source information. The 7x7mm 48-LQFP footprint is useful where board area is constrained. Designers should compare digital and analog supplies, isolate the I2S bus from output-filter components, and confirm the DAC's output architecture before selecting passive filtering and speaker-driver circuitry.

Automotive Audio Head Unit
The PCM1602Y's six-channel, 24-bit, 192kHz conversion capability can suit a multichannel automotive audio head unit when the exact operating grade and environmental requirements are approved for that platform. Six DAC channels allow the head unit to drive multiple speaker zones without an equivalent number of discrete converter packages. The I2S interface supports connection to a vehicle audio processor, subject to compatible clocking and data mapping. Automotive use requires careful review of temperature range, electromagnetic interference, supply transients, and any AEC-Q100 qualification; those attributes were not available in the supplied verified data.
Được đề xuất
Professional Audio Playback
The PCM1602Y can support professional playback equipment requiring six digital-to-analog channels with high source resolution. Its maximum 192kHz sampling rate accommodates high-resolution studio material, and the six-channel output simplifies monitor-controller and multichannel playback designs. For professional signal paths, use the manufacturer's recommended analog filters, verify output-noise and distortion data against the system specification, and keep digital routing away from sensitive analog nodes. The converter's I2S interface also makes it suitable for systems whose audio engine already produces standard I2S channel data.
Được đề xuất
Digital Audio Interface and Recorder
The PCM1602Y can be paired with a digital audio interface or recorder that accepts or produces multichannel I2S data. In a monitoring or recording system, the converter provides six analog outputs for monitoring, while the companion interface handles the digital side of the signal path. Matching sample rate, bit depth, clock source, and channel ordering is essential because unsupported master-clock relationships can cause invalid conversion behavior. PCB placement should keep the I2S traces short and properly referenced, with separate analog and digital supply decoupling close to their respective pins.
Được đề xuất
Multi-Zone Audio Distribution
PCM1602Y is suitable for multi-zone audio distribution when a central controller must produce several synchronized analog outputs. Its six channels can serve independent listening zones or groups of powered speakers, while 192kHz sampling supports high-resolution source formats. The host controller must serialize the correct channel data over I2S and maintain a valid clock relationship throughout playback. Designers should also plan for output-channel muting, gain control, amplifier integration, and independent grounding strategies where the zones use different amplifier grounds or power domains.

Ghi chú thiết kế
Place the required input, output, and supply-decoupling capacitors directly beside their associated PCM1602Y pins. Keep the 48-LQFP footprint and exposed-pad layout consistent with the official TI land pattern. Route the I2S data and clock traces away from the analog output section, and provide a continuous, low-impedance ground reference so the six-channel outputs share a stable return path.
Treat the analog and digital supplies as separate power domains and follow the datasheet limits for voltage, sequencing, and decoupling. The verified information identifies a 3V-to-3.6V analog range and a 5V digital supply, but it does not establish every transient or startup constraint. Confirm those details before power-up and include local bulk and high-frequency bypass capacitance where the manufacturer reference design requires it.
The I2S interface must receive valid 24-bit data and a supported clock relationship for the selected 192kHz operating mode. Use short, impedance-controlled traces, avoid unnecessary stubs, and place clock-generation or synchronization circuits close to the source when timing margin is limited. Incorrect clock ratios or channel ordering can create invalid conversion output even when the physical audio data appears correct.
Do not assume that all six outputs have identical circuit requirements until the analog-output pinout and recommended filter topology are confirmed from the official datasheet. Also do not infer automotive qualification, RoHS status, or an exact operating-temperature range from generic distributor descriptions. Those attributes must be checked against the ordered MPN before schematic release or production qualification.
Thông tin tuân thủ
The supplied distributor and manufacturer-result data do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These fields therefore remain unknown rather than being inferred.
