AD5410/AD5420 are low cost, precision, single-channel, 12/16-bit, serial input, 4mA to 20mA, current source DACs, supporting HART network connectivity.
The AD5410 and AD5420 are low‑cost, precision, single‑channel current‑source DACs offering 12‑ or 16‑bit resolution with programmable output ranges of 0‑24 mA, 0‑20 mA, or 4‑20 mA. They include on‑chip reference, fault detection, and support flexible serial interfaces such as SPI, Microwire, and QSPI.
The document details electrical specifications, absolute maximum ratings, timing diagrams, pin functions, and example industrial HART‑compatible applications. Ordering information and package dimensions for the 24‑lead TSSOP and 40‑lead LFCSP options are also provided.
