Product details
Overview
D2-92683-QR-T from Renesas Electronics is a 72-pin QFN System-on-Chip digital audio processor and Class-D amplifier controller, integrating 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. It delivers SNR >110dB and THD+N <0.01% in powered speaker and home theater applications.
For engineers reviewing the D2-92683-QR-T datasheet, D2-92683-QR-T pinout, D2-92683-QR-T application, or D2-92683-QR-T equivalent, key selection considerations include its 72 Ld QFN package, -10°C to +85°C operating range, Dolby Digital/AC3 decoder exclusion (vs. D2-92684-QR), and absence of integrated stereo ADC - requiring external analog front-end for ADC-based designs.
Technical Context
The D2-92683-QR-T implements a configurable multi-channel audio signal path with real-time amplifier control supporting bridged, half-bridged, and BTL topologies. Its embedded asynchronous sample rate converter enables flexible clock domain bridging across up to eight input channels.
It features dynamic level-dependent timing, internal noise shaping, and high-resolution operation to achieve >110dB SNR and <0.01% THD+N. The device uses a 24.576MHz crystal oscillator and PLL locked to 294.912MHz for core and PWM timing, with programmable PWM output configurations enabling scalable multi-channel output power capacity.

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-T | Identical 72-pin QFN package and pinout; adds licensed Dolby Digital/AC3 decoder support | Required for systems needing native AC3 bitstream decoding (e.g., broadcast TV tuners) | Select D2-92684-QR-T only if Dolby Digital licensing is secured; otherwise D2-92683-QR-T reduces cost and avoids royalty obligations |
| D2-92633-LR | 128-pin LQFP package; includes integrated stereo ADC and two S/PDIF inputs (vs. one) | Better suited for designs requiring analog line-in (e.g., legacy audio sources) and dual digital inputs | Choose D2-92633-LR when analog input capability or second S/PDIF input is mandatory; D2-92683-QR-T saves board space and cost where those features are unused |
Compared with D2-92684-QR-T, D2-92683-QR-T omits Dolby Digital licensing but retains identical PWM, SRC, and GUI v3 functionality - making it optimal for cost-sensitive, non-AC3 applications. Against D2-92633-LR, it trades ADC and extra S/PDIF for smaller footprint and lower thermal load in space-constrained powered speakers.

FAQ
What audio decoders does the D2-92683-QR-T support?
The D2-92683-QR-T supports D2 Audio DSP sound enhancement algorithms (included at no license cost) but does not include Dolby Digital/AC3 decoding. That feature is exclusive to D2-92684-QR-T and requires a third-party license. The D2-92683-QR-T processes PCM via S/PDIF and I²S, and relies on upstream devices for AC3 bitstream decoding.
Does the D2-92683-QR-T include an integrated ADC?
No, the D2-92683-QR-T does not include an integrated ADC. Unlike the D2-3 family (e.g., D2-92633-LR), the D2-3S family - which includes D2-92683-QR-T - omits the stereo analog-to-digital converter. External ADCs must be used for analog audio inputs, while digital inputs (I²S, S/PDIF) are fully supported.
What is the maximum number of I²S channels supported by the D2-92683-QR-T?
The D2-92683-QR-T supports up to eight I²S input channels, configurable either as eight inputs or six inputs plus two outputs. This flexibility allows system designers to adapt the D2-92683-QR-T to varying source and zone requirements without hardware changes - all managed through the D2 Audio Customization GUI v3.
What package type and thermal characteristics apply to the D2-92683-QR-T?
The D2-92683-QR-T uses a 72-pin QFN package (L72.10x10F) with exposed thermal pad. Its thermal resistance is θJA = 22°C/W and θJC = 0.80°C/W, enabling efficient heat transfer to the PCB. This makes the D2-92683-QR-T suitable for thermally constrained consumer enclosures where airflow is limited.
How is real-time amplifier protection implemented in the D2-92683-QR-T?
The D2-92683-QR-T provides eight dedicated PROTECT[0–7] inputs for monitoring external Class-D power stage faults. These pins detect overcurrent, overtemperature, and DC offset conditions, triggering hardware-level shutdown and automatic recovery sequences - all without CPU intervention - ensuring robust speaker protection in powered speaker and soundbar applications.
