Product Overview: AD1938YSTZ by Analog Devices Inc.

The AD1938YSTZ is a high-performance, audio codec from Analog Devices Inc. that provides an integrated solution for sophisticated audio processing applications. It is designed to deliver superior sound quality in a wide range of consumer and professional audio systems such as home theater systems, mixing consoles, and digital audio workstations.

This codec features a multi-channel architecture, with four DACs (Digital-to-Analog Converters) and four ADCs (Analog-to-Digital Converters), making it an ideal choice for systems requiring high channel count. The DACs provide 24-bit conversion at sample rates up to 192 kHz, ensuring high fidelity playback of digital audio content. The ADCs also support 24-bit data and sample rates up to 192 kHz, enabling precise and accurate recording of analog signals.

The AD1938YSTZ operates on a single 3.3V power supply for the DACs and ADCs, with a separate 1.8V supply for the digital interface to minimize digital noise. It features a flexible serial data interface that supports I²S, left-justified, and TDM formats, allowing for easy integration with a variety of DSPs and microcontrollers.

One of the key advantages of the AD1938YSTZ is its on-chip PLL (Phase-Locked Loop), which generates the required internal clock signals from an external reference clock. This feature simplifies the clocking scheme of audio systems by reducing the need for multiple external clock sources.

The device also boasts a range of additional features, such as programmable input and output levels, flexible mixing, mute functions, and a volume control. These functionalities offer designers the ability to customize their audio signal chain to meet specific application requirements.

Encased in a 48-lead LQFP (Low Profile Quad Flat Package), the AD1938YSTZ is engineered for space-constrained applications while still offering robust performance. Its compact footprint and comprehensive feature set make it an excellent choice for designers looking to enhance the audio capabilities of their systems without compromising on space or sound quality.

Overall, the AD1938YSTZ from Analog Devices Inc. is a powerful audio codec that provides a high level of integration, performance, and flexibility, making it a go-to choice for a multitude of audio processing applications.
