ANALOG DEVICES 4 ADC/8 DAC with PLL 192 kHz 24-Bit Codec AD1938 English products handbook Rev D
The AD1938 is a high‑performance single‑chip audio codec that provides four analog‑to‑digital converters and eight digital‑to‑analog converters in a 48‑lead LOFP package. It operates from a 3.3 V supply and includes an on‑board PLL for master‑clock generation, supporting sample rates from 8 kHz to 192 kHz.
Key features include low EMI design, 108 dB DAC and 107 dB ADC dynamic range, software‑controllable volume with click‑less mute, SPI‑based control, and qualification for automotive applications. Typical applications are automotive audio systems, home theater, set‑top boxes, and digital audio effects processors.
