| Part Number | AD1939YSTZRL |
|---|---|
| Manufacturer | Analog Devices Inc. (ADI) |
| Category | Integrated Circuits (ICs) > ADC/DAC – Special Audio CODECs |
| Brief Description | 4 ADC/8 DAC, 192 kHz, 24-bit audio codec with integrated PLL, LQFP-64 tape & reel packaging for SMT mass production |
| Stock Status | In Stock |
| Origin | Original Factory |
Product Overview
The AD1939YSTZRL is a high-performance multi-channel audio CODEC by ADI, integrating 4 differential ADC inputs, 8 differential DAC outputs and an on-chip PLL. It supports 24-bit PCM audio up to 192kHz sampling rate via Sigma-Delta architecture, with dual SPI/I2C control bus and full differential analog paths to suppress EMI noise. Suitable for automotive audio, professional recording and home theater systems; RL suffix stands for tape & reel packaging for mass SMT production.
Core Advantages
High Channel Integration + Built-in PLL Clock
Combines 4 ADC + 8 DAC on single chip; integrated PLL removes external high-frequency crystal, saving PCB space and clock synchronization workload.
Industry-Leading Audio Dynamic Range
ADC typical 107dB (min 105dB), DAC typical 112dB (min 110dB) A-weighted dynamic range for high-fidelity audio playback.
Full Differential Analog Signal Path
Differential I/O design strongly rejects EMI interference, fit for noisy automotive & industrial mixed-signal circuits.
Dual SPI & I2C Control Interface
Dual serial bus supports flexible register configuration, independent channel volume tuning and clickless mute.

Frequently Asked Questions
Q1: Are AD1939YSTZRL genuine new original?
A: All stock are brand-new original from ADI, shipped in anti-static tape & reel. Every batch passes pin & visual inspection before delivery.
Q2: What does RL suffix mean?
A: RL stands for tape & reel for automated SMT mass production. AD1939YSTZ (without RL) is tray packaging for prototype sampling.
Q3: Can it work without external master crystal?
A: Yes. The built-in PLL generates all audio clocks from LRCLK, no external high-frequency crystal needed.
Q4: How to get datasheet and bulk quotation?
A: Fill the inquiry form with your project demand and order quantity, we will send datasheet, pinout diagram and tiered price within 24h.
