The AD1939YSTZ is a high-performance, single-chip codec from Analog Devices Inc. that provides four digital-to-analog converters (DACs) and eight analog-to-digital converters (ADCs), making it an ideal choice for professional and consumer audio applications. This codec operates on a 5 V power supply for the analog circuitry and a 3.3 V supply for the digital interface, offering an exceptional dynamic range and very low distortion characteristics.

Key Features:

• High-Quality Audio: The AD1939YSTZ provides 24-bit conversion on all channels, ensuring pristine audio quality with sample rates up to 192 kHz for DACs and 96 kHz for ADCs.
• Flexible I/O: With four DACs and eight ADCs, the device supports a variety of I/O configurations, perfect for complex audio systems requiring multiple input and output channels.
• Low Latency: The codec features a low-latency ADC and DAC architecture, which is crucial for real-time audio processing applications where timing is critical.
• Integrated PLL: An on-chip phase-locked loop (PLL) provides flexible clocking options, reducing the need for external clock management components.
• Multi-channel Support: The AD1939YSTZ supports TDM (Time Division Multiplexed) interfaces, allowing multiple audio channels to be carried over a single digital audio interface, which simplifies PCB design and reduces system complexity.

Applications:

The AD1939YSTZ is suited for a wide range of applications, including:

• Professional audio mixing consoles
• Digital audio effects processors
• Automotive audio systems
• Home theater systems
• Studio recording equipment
