Product details
Overview
ADAV801ASTZ-REEL from Analog Devices is a stereo audio codec IC designed for DVD/CD recorders, integrating ADC (102 dB DR @ 48 kHz), DAC (101 dB DR @ 48 kHz), and sample rate converter (140 dB DR) in a single 64-lead LQFP package. It supports asynchronous dual-domain operation with S/PDIF I/O, SPI control, and programmable gain amplifiers for analog input conditioning.
For engineers reviewing the ADAV801ASTZ-REEL datasheet, ADAV801ASTZ-REEL pinout, ADAV801ASTZ-REEL application, or ADAV801ASTZ-REEL equivalent, key selection criteria include simultaneous 24-bit stereo ADC/DAC performance, 8–192 kHz SRC flexibility, integrated DIR/DIT, and commercial-grade (−40°C to +85°C) operation in recordable optical storage systems.
Technical Context
The ADAV801ASTZ-REEL implements Σ-Δ modulation with Sinc⁵ + triple half-band decimation for ADC and interpolation filtering for DAC, enabling high-fidelity audio conversion. Its dual PLL architecture generates SYSCLK1–SYSCLK3 (256× to 768× fS) and supports independent MCLK sourcing for ADC and DAC domains.
It features fully configurable digital data paths via a switching matrix, allowing SRC output routing to DAC, main/auxiliary record channels, or DIT. The ALC block operates on ADC output with 0.5 dB gain steps and attack/recovery timing control-distinct from digital volume control, which applies post-conversion scaling.

Applications
| DVD Recordable System | CD-R/W Recorder |
|---|---|
Use Scenario: Capturing analog line-in or digital coaxial audio into MPEG-2 or Dolby Digital streams for burning onto DVD-R. IC Role / Device Role / Timing Role: ADC digitizes analog inputs; SRC aligns incoming 44.1 kHz CD audio to 48 kHz DVD system clock; DIT outputs encoded bitstream to laser controller. Use Value: Single-chip integration reduces BOM count and PCB area while maintaining >100 dB dynamic range across both recording and playback paths. | Use Scenario: Simultaneous playback of CD-DA audio and recording of external analog source onto CD-RW media. IC Role / Device Role / Timing Role: DAC reproduces CD-DA audio at 44.1 kHz; ADC samples line-in at 44.1 kHz or 48 kHz; SRC bridges mismatched rates if needed. Use Value: Asynchronous operation avoids clock jitter accumulation between playback and record domains, preserving audio clarity during real-time dubbing. |
| Multi-Format Optical Drive Controller | Digital Audio Interface Bridge |
Use Scenario: Supporting DVD+R, DVD-R, CD-R, and CD-RW in one drive platform with shared audio subsystem. IC Role / Device Role / Timing Role: Configurable sample rate support (32–192 kHz) and multiple digital I/O ports enable format-agnostic audio handling. Use Value: Reduces firmware complexity by offloading SRC, ALC, and format-specific clock management to hardware. | Use Scenario: Converting S/PDIF input to I²S for SoC-based audio processing, or vice versa for legacy device interfacing. IC Role / Device Role / Timing Role: DIR receives S/PDIF, SRC converts to target rate, DAC outputs analog or I²S output port sends to host processor. Use Value: Eliminates need for discrete transceivers and external SRC ICs-reducing latency and component count in compact designs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar stereo audio codec applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AK4589VN | Lower ADC DR (98 dB), no integrated ALC, requires external crystal for all clocks | Lacks automatic level control and SRC flexibility; suited for fixed-rate playback-only systems | Choose AK4589VN only if cost sensitivity outweighs need for ALC and multi-rate SRC in recorder designs |
| CS4272-KQZ | Higher THD+N (−95 dB vs −91 dB), no DIR/DIT, supports only up to 96 kHz SRC | Missing S/PDIF interface limits use in optical disc recorders requiring direct coaxial/optical I/O | Select CS4272-KQZ for non-optical applications where S/PDIF is unnecessary and 96 kHz max rate suffices |
Compared with AK4589VN and CS4272-KQZ, ADAV801ASTZ-REEL uniquely combines ALC, full S/PDIF transceiver, and 8–192 kHz SRC in one package-making it the only option qualified for DVD-recordable system reference designs requiring simultaneous analog capture, digital format conversion, and optical interface compliance.

FAQ
What is the maximum sample rate supported by the ADAV801ASTZ-REEL's sample rate converter?
The ADAV801ASTZ-REEL's sample rate converter supports input and output rates from 8 kHz to 192 kHz, with maximum upsampling ratio of 1:8 and downsampling ratio of 7.75:1. This enables seamless conversion between CD (44.1 kHz), DVD (48 kHz), and high-resolution DVD-Audio (96/192 kHz) formats without external circuitry.
Does the ADAV801ASTZ-REEL require an external crystal oscillator?
The ADAV801ASTZ-REEL can operate with either an external crystal (XIN/XOUT, 27 or 54 MHz) or an external master clock (MCLKI, up to 54 MHz). Its dual PLL architecture generates all required internal clocks-including SYSCLK1–SYSCLK3 and MCLKO-eliminating the need for additional oscillators in most DVD/CD recorder designs.
How does the automatic level control (ALC) function in the ADAV801ASTZ-REEL differ from its digital volume control?
The ALC in ADAV801ASTZ-REEL adjusts analog PGA gain before ADC conversion to prevent clipping, while digital volume control scales already-digitized samples post-conversion. Using ALC with volume control simultaneously degrades signal integrity; the datasheet explicitly advises disabling volume control when ALC is active to preserve dynamic range.
Can the ADAV801ASTZ-REEL handle both S/PDIF input and output concurrently?
Yes-the ADAV801ASTZ-REEL integrates a dedicated Digital Interface Receiver (DIR) and Digital Interface Transmitter (DIT) that operate independently. DIR accepts S/PDIF input at 27.2–200 kHz, while DIT outputs compliant IEC 60958 frames, enabling simultaneous digital passthrough, format conversion, or loopback in optical recorder architectures.
What is the thermal pad configuration for the ADAV801ASTZ-REEL's LQFP package?
The ADAV801ASTZ-REEL uses a 64-lead LQFP package with an exposed thermal pad on the underside. Per Analog Devices' layout guidelines, this pad must be soldered to a large copper pour connected to AGND and/or DGND planes using multiple thermal vias to ensure proper heat dissipation and EMI suppression in high-density optical drive PCBs.
