The document describes the features and characteristics of the AD5384 product, including guaranteed monotonic INL error, built-in reference voltage and amplifier, temperature range, user interfaces, and integrated functions.
The AD5384 is a complete single‑supply, 40‑channel, 14‑bit DAC available in a 100‑lead CSPBGA package. All channels include on‑chip rail‑to‑rail output amplifiers and an internal 1.25 V/2.5 V reference with 10 ppm/°C temperature coefficient. The device supports SPI, QSPI, Microwire and DSP‑compatible serial interfaces, allowing high‑speed data transfer and simultaneous output updates.
The datasheet provides full specifications, including resolution, output voltage range, power requirements, and timing characteristics. It also describes functional blocks, special function registers, hardware functions, and application examples such as optical attenuators and MEMS‑based optical switches. Ordering information and package dimensions are included for system designers.
