The AD5412/AD5422 are low cost, precision, fully integrated12-/16-bit digital-to-analog converters (DAC) offering a programmable current source and programmable voltage 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 LFCSP version of this product has a CAP2 pin so that the HART signals can be coupled onto the current output of the AD5412/AD5422.
Voltage output is provided from a separate pin that can be configured to provide 0 V to 5 V, 0 V to 10 V, ±5 V, or ±10 V output ranges; an overrange of 10% is available on all ranges.
Analog outputs are short and open-circuit protected and can drive capacitive loads of 1 μF.
The device operates with an AVDD power supply range from 10.8 V to 40 V. Current loop compliance voltage is 0 V to AVDD − 2.5 V.
The flexible serial interface is SPI- and MICROWIRE™-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. The part also includes an asynchronous clear pin (CLEAR) that sets the outputs to zero-scale/midscale voltage output or the low end of the selected current range.
The total output error is typically ±0.01% in current mode and ±0.01% in voltage mode.
Applications
- Process controls
- Actuator controls
- PLC
- HART network connectivity (LFCSP package only)
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
