AD5410/AD5420 is a single-channel, 12-/16-bit, serial input, 4 mA to 20 mA current source DAC. It features 12-/16-bit resolution and monotonicity, current output ranges of 4 mA to 20 mA, 0 mA to 20 mA, or 0 mA to 24 mA, flexible serial digital interface, on-chip output fault detection, and on-chip reference voltage.
The AD5410 and AD5420 are low‑cost, precision, fully integrated 12‑/16‑bit current‑output DACs designed for industrial process‑control applications. They provide programmable output ranges of 0‑20 mA, 4‑20 mA, or 0‑24 mA, include on‑chip reference and fault detection, and operate from a wide supply voltage range.
The document includes a feature list, functional block diagram, detailed electrical specifications, timing diagrams, pin‑out tables, absolute maximum ratings, ESD precautions, and an example industrial analog‑output application. Ordering information and package dimensions are also provided.
| Output current range | 0 mA to 24 mA |
|---|---|
| Resolution | 12 bits (AD5410) / 16 bits (AD5420) |
| Supply voltage (AVpp) range | 10.8 V to 40 V (24‑lead TSSOP) / 10.8 V to 60 V (40‑lead LFCSP) |
| Operating temperature range | ‑40 °C to +85 °C |

The devices can be programmed for output ranges of 0 mA to 20 mA, 4 mA to 20 mA, or 0 mA to 24 mA.
The DACs support SPI, MICROWIRE, QSPI, and DSP‑compatible serial interfaces and can operate in 3‑wire mode.
The devices are rated for industrial temperature operation from –40 °C to +85 °C.
The AVpp supply voltage can be between 10.8 V and 40 V for the TSSOP package (up to 60 V for the LFCSP package).
