Use Scenario: Playback path in DVD-ROM or Blu-ray players where decoded digital audio must be converted to analog for analog outputs (RCA, headphone). IC Role / Device Role / Timing Role: DAC reconstructs PCM audio; volume control adjusts output level; FILTD pin stabilizes reference for low-noise analog output. Use Value: 101 dB DAC DR and <0.005 dB passband ripple ensure audiophile-grade analog output fidelity meeting EIAJ CP-340 specifications. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar stereo audio codec applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AK4583EN | 24-bit ADC/DAC, 98 dB DR, no integrated SRC or S/PDIF; requires external clock generator and resampler. | Limited to fixed-sample-rate systems (e.g., 44.1/48 kHz only); unsuitable for mixed-domain DVD/CD recorders needing SRC. | Select AK4583EN only if system uses single sample rate and external ASRC is already present - avoids over-spec'ing for simpler designs. |
| CS4272-CQZ | 24-bit ADC/DAC, 110 dB DR, integrated SRC and S/PDIF, but lacks ALC and PGA - requires external front-end amplification. | Better suited for playback-dominant systems (e.g., AV receivers); less ideal for record-focused DVD burners needing automatic gain control. | Choose CS4272-CQZ when highest DAC DR is prioritized and analog input conditioning is handled externally - e.g., in premium home theater players. |
Compared with AK4583EN and CS4272-CQZ, ADAV801ASTZ uniquely combines ALC, PGA, integrated S/PDIF, and high-DR SRC in one package - making it the only option that satisfies full DVD-recordable system requirements without supplemental ICs.

FAQ
What is the maximum supported sample rate for the ADAV801ASTZ DAC?
The ADAV801ASTZ DAC supports playback at up to 192 kHz, with measured dynamic range of 100 dB (A-weighted) and THD+N of −90 dB at that rate. This capability enables high-resolution audio playback in next-generation DVD-Audio and SACD-compatible recorders, and is confirmed in Table 2 of the Rev. A datasheet under DAC SECTION specifications.
Does the ADAV801ASTZ include automatic level control (ALC) for recording?
Yes, the ADAV801ASTZ includes a fully programmable ALC block in its ADC section that dynamically adjusts PGA gain to prevent clipping during analog input recording. As described in the General Description and Functional Description sections, ALC monitors ADC output levels and reduces gain in 0.5 dB steps when thresholds are exceeded - a key feature for unattended DVD/CD recording applications.
Can the ADAV801ASTZ operate with independent sample rates for ADC and DAC?
Yes, the ADAV801ASTZ supports fully asynchronous operation: its ADC and DAC can run at different sample rates simultaneously (e.g., 44.1 kHz ADC input, 48 kHz DAC output), with the integrated 24-bit sample rate converter (SRC) handling domain bridging. This is explicitly stated in the FEATURES list and detailed in the SRC Section of the datasheet.
What digital audio interfaces does the ADAV801ASTZ support?
The ADAV801ASTZ supports I²S-compatible record/playback/auxiliary digital ports, plus full IEC 60958-compliant S/PDIF input (DIR) and output (DIT). All interfaces operate across 27.2–200 kHz sample rates, with DIR featuring a dedicated PLL for jitter tolerance - confirmed in the FEATURES, DIR SECTION, and DIT SECTION tables of the datasheet.
Is the ADAV801ASTZ pin-compatible with other members of the ADAV80x family?
No, the ADAV801ASTZ is not pin-compatible with other ADAV80x variants such as ADAV803 or ADAV805. The Rev. A datasheet specifies only the ADAV801 device in the 64-lead LQFP package; pin configurations, register maps, and feature sets differ across the family - making direct substitution impossible without PCB redesign and firmware updates.
