Product details
Overview
D2-92683-QR from Renesas Electronics is a 72-pin QFN System-on-Chip (SoC) digital audio processor and Class-D amplifier controller for multi-channel powered audio systems. It integrates a 12-channel PWM engine, 8-channel sample rate converter, S/PDIF I/O, four asynchronous I²S inputs, and D2 Audio DSP sound enhancement algorithms - delivering >110dB SNR and <0.01% THD+N in high-fidelity soundbar and home theater applications.
For engineers reviewing the D2-92683-QR datasheet, D2-92683-QR pinout, D2-92683-QR application, or D2-92683-QR equivalent, key selection criteria include its 72 Ld QFN package, -10°C to +85°C operating range, support for Dolby Digital/AC3 (via external license), real-time amplifier protection, and compatibility with the D2 Audio Customization GUI v3 for configurable audio signal routing and processing.
Technical Context
The D2-92683-QR implements a fully programmable DSP core running at 147.456 MHz with dynamic register addressing architecture, enabling real-time reconfiguration of audio paths including equalization, dynamic range compression, mixing, and filtering. Its embedded 8-channel asynchronous sample rate converter supports independent input/output sampling rates up to 192 kHz.
It features a 12-channel digital PWM engine with programmable timing, noise shaping, and BTL/half-bridge topology support - directly controlling external Class-D power stages. Amplifier protection includes overcurrent, overtemperature, and undervoltage detection with automatic recovery, managed via dedicated PROTECT[0–7] pins and synchronized PWM output control.

Applications
| DTV & Soundbar Systems | Home Theater in a Box (HTiB) |
|---|---|
|
Use Scenario: Compact all-in-one soundbar with integrated 5.1-channel amplification and virtual surround processing. IC Role / Device Role / Timing Role: Central audio SoC handling digital input demuxing, DSP-based spatial rendering, and 12-channel PWM drive for discrete Class-D amps. Use Value: Eliminates need for separate DAC, DSP, and amplifier controller ICs - reduces BOM count and PCB area by >40%. |
Use Scenario: Entry-level HTiB with HDMI ARC input, Bluetooth audio, and 5.1 speaker outputs. IC Role / Device Role / Timing Role: Audio processor managing S/PDIF extraction, Dolby Digital decoding (licensed), and real-time volume leveling across channels. Use Value: Enables certified Dolby playback with single-chip integration - avoids dual-IC licensing and synchronization complexity. |
| Powered Speaker Systems | Multi-Room Distributed Audio |
|
Use Scenario: Active studio monitor with dual 3-way drivers per enclosure and built-in room correction. IC Role / Device Role / Timing Role: Multi-channel audio processor performing per-driver EQ, phase alignment, and adaptive limiting before PWM output. Use Value: Supports independent 3-way crossover and driver-specific tuning - replaces FPGA+DSP solutions costing 3× more. |
Use Scenario: Whole-home audio hub distributing synchronized stereo/mono streams to 4 zones with local volume control. IC Role / Device Role / Timing Role: Audio router and resampler receiving network-streamed PCM and converting to zone-specific sample rates via embedded SRC. Use Value: Hardware-accelerated 8-channel SRC allows simultaneous 4-zone playback at different rates (e.g., 44.1/48/88.2/96 kHz) without CPU overhead. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar digital audio processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| D2-92684-QR | Identical D2-3S package and pinout; adds licensed Dolby Digital/AC3 decoder firmware | Required for certified Dolby playback; no hardware change needed | Select D2-92684-QR only if Dolby licensing is secured and AC3 bitstream decoding is mandatory |
| TAS5825M (TI) | 12-channel Class-D amplifier + integrated DSP; lacks S/PDIF RX/TX and 8-channel SRC | Better suited for line-powered speakers without optical input; no Dolby or multi-rate SRC support | Choose TAS5825M when S/PDIF is unnecessary and cost-sensitive designs prioritize integrated gate drivers |
Compared with D2-92683-QR, D2-92684-QR adds Dolby Digital decode capability without layout changes, while TAS5825M trades S/PDIF and SRC flexibility for lower system cost and integrated power-stage drivers - making it viable only where optical input and multi-format resampling are omitted.

FAQ
What audio decoders does the D2-92683-QR support natively?
The D2-92683-QR includes D2 Audio DSP sound enhancement algorithms (bass management, virtual surround, loudness compensation) without additional licensing. It does not include native Dolby Digital/AC3 decoding - that capability is exclusive to D2-92684-QR and requires a third-party license. All D2-3S devices support PCM, DTS, and MPEG audio via S/PDIF passthrough and internal processing.
Does the D2-92683-QR require an external ADC?
Yes, the D2-92683-QR does not integrate an analog-to-digital converter. Unlike the 128-pin D2-3 family (e.g., D2-92633-LR), the D2-3S family - including D2-92683-QR - omits the stereo ADC and ADCREF pins. Analog inputs must be digitized externally using a separate ADC IC before feeding I²S or S/PDIF data to D2-92683-QR.
What is the maximum supported sample rate for the D2-92683-QR's I²S interfaces?
The D2-92683-QR supports I²S data rates up to 192 kHz per channel across its four asynchronous I²S ports. Each port can be independently configured for master or slave mode, and the embedded 8-channel sample rate converter handles rate mismatches between inputs, outputs, and internal DSP clock domains without external buffering.
Can the D2-92683-QR drive Class-D power stages directly?
No, the D2-92683-QR outputs 12 digital PWM signals - not analog or gate-drive voltages. It requires external Class-D power stages (e.g., IRS2092S, TAS5381) or gate drivers to convert its PWM outputs into amplified audio. The device provides real-time protection signaling (PROTECT[0–7]) and PWM synchronization (PWMSYNC, PSSYNC) for safe, coordinated power-stage control.
Is the D2-92683-QR pin-compatible with any other Renesas audio SoCs?
Yes, D2-92683-QR is pin-compatible and functionally identical to D2-92684-QR within the D2-3S family - differing only in pre-programmed firmware (Dolby decode enabled in D2-92684-QR). It is not pin-compatible with the 128-pin D2-3 family (e.g., D2-92633-LR); those use different packages, pin counts, and include integrated ADCs.
