AD5410/AD5420 is a 12/16-bit, 4mA~20mA current output, 12/16-bit DAC with SPI/I2C/MICROWIRE interface. It can be used for various current source applications, including current drivers, battery dischargers, battery chargers, current detectors and current loop control.
The AD5410/AD5420 family provides a fully integrated, low‑power DAC solution for industrial control, PLC, and instrumentation applications. Both devices support multiple serial interfaces (SPI, Microwire, QSPI, and PDSP) and offer programmable current‑output ranges of 4 mA‑20 mA, 0 mA‑20 mA, or 0 mA‑24 mA.
Typical specifications include a 12‑bit resolution for AD5410 and 16‑bit for AD5420, supply voltage from 10.8 V to 26.4 V, and operation over –40 °C to +85 °C. The datasheet also details pin configurations, timing diagrams, and recommended layout guidelines. This manual is written in Japanese.
