The AD193X family are high performance, single-chip codecs that provide 4 ADCs with differential input and 8 DACs with either single-ended or differential output using ADI’s patented multibit sigma-delta architecture.
The AD1936 is a high‑performance, single‑chip audio codec offering four differential ADCs and eight DACs with 24‑bit resolution. It operates from a single 3.3 V supply and includes a PLL for flexible master‑clock generation, supporting sample rates from 8 kHz to 192 kHz.
