AD1937 is a high performance single-chip codec that provides four ADCs and eight DACs, supports 192kHz sample rate and 24-bit resolution. Features are low EMI design, support I2C control, have log volume control and autoramp function. It is suitable for automotive audio systems, home theater systems, set-top boxes and digital audio effects processors.
The AD1937 audio codec from Analog Devices integrates four differential ADCs and eight differential DACs in a single 64‑lead LQFP package. It operates from a single 3.3 V supply and includes an on‑chip PLL for flexible master‑clock generation, supporting sample rates from 8 kHz to 192 kHz.
The datasheet provides detailed specifications, timing diagrams, digital filter characteristics, and absolute maximum ratings, along with ordering information for both commercial and automotive‑qualified versions of the device.
