The ADAU1328 is a high performance single-chip codec that provides two analog-to-digital converters (ADCs) with differential input and eight digital-to-analog converters (DACs), supporting 24 bits and 8 kHz to 192 kHz sample rates.
The ADAU1328 codec from Analog Devices provides two differential ADCs and eight single‑ended DACs in a single 48‑lead LQFP package. It features an on‑chip PLL for master‑clock generation, low‑EMI design, and operates from a single 3.3 V supply.
The document includes detailed specifications, functional block diagrams, timing information, absolute maximum ratings, and ordering details, making it a comprehensive reference for designers integrating the codec into audio systems such as home‑theater, set‑top boxes, and digital audio processors.
