The AD5410 are low cost, precision, fully integrated 12-bit converters offering a programmable current source output designed to meet the requirements of industrial process control applications. The output current range is programmable at 4 mA to 20 mA, 0 mA to 20 mA, or an overrange function of 0 mA to 24 mA. The output is open-circuit protected. The device operates with a power supply (AVDD) range from 10.8 V to 60 V. Output loop compliance is 0 V to AV_DD − 2.5 V.

The flexible serial interface is SPI, MICROWIRE™, QSPI™, and DSP compatible and can be operated in 3-wire mode to minimize the digital isolation required in isolated applications.

The device also includes a power-on reset function, ensuring that the device powers up in a known state, and an asynchronous CLEAR pin that sets the output to the low end of the selected current range.

The total unadjusted error is typically ±0.01% FSR.
