Description
The AD1939YSTZRL is a high-performance, 8-channel audio codec from Analog Devices, designed for professional and consumer audio applications. It features 24-bit resolution and supports sample rates up to 192 kHz, ensuring high-fidelity audio processing.
Key features include:
- 8 DACs (113 dB SNR) and 4 ADCs (105 dB SNR)
- Flexible serial ports (I²S, TDM, left-justified)
- Low power consumption (typ. 300 mW)
- Integrated PLL for clock generation
The device supports SPI control for configuration and is housed in a 64-lead LQFP package. It’s ideal for AV receivers, soundbars, and multi-channel audio systems.
The "RL" suffix indicates tape-and-reel packaging for automated assembly. Its robust design and high dynamic range make it suitable for demanding audio applications.
For detailed specs, refer to the datasheet on Analog Devices' website.
