The AD5410/AD5420 is a low-cost, precision, fully integrated 12-/16-bit converter offering a programmable current source output designed for control applications.
The AD5410 and AD5420 are low‑cost, precision, fully integrated current‑output DACs offering 12‑ or 16‑bit resolution with programmable output ranges of 0‑20 mA, 4‑20 mA, or 0‑24 mA. They feature an on‑chip reference, fault detection, and a flexible serial interface compatible with SPI, Microwire, QSPI, and DSP modes.
The document includes detailed specifications, pin‑out tables, timing diagrams, absolute maximum ratings, and application notes for industrial analog output designs. Ordering information, package options (24‑lead TSSOP and 40‑lead LFCSP), and mechanical drawings are also provided.
