Analog DevicesEVAL-CN0204-SDPZ

EVAL-CN0204-SDPZ is Flexible, High Voltage, High Accuracy, Low Drift PLC/DCS Analog Output Module Evaluation Board. CN-0204 Circuit provides a full function, high voltage (up to 44 V), flexible, programmable analog output solution that meets most requirements for programmable logic controller (PLC) and distributed control system (DCS) applications.

The AD5662 low power (0.75 mW typical @ 5 V), rail-to-rail output, 16-bit nanoDAC® device and the AD5751 industrial current/voltage output driver are well matched with respect to input and output voltage ranges, as well as reference voltage requirements.

The ADR444, with low drift (3 ppm/℃ maximum for B grade), high initial accuracy (0.04% maximum for B grade), and low noise (1.8 μV p-p typical, 0.1 Hz to 10 Hz), provides the reference voltage for both the AD5751 and AD5662 and guarantees ultralow noise, high accuracy, and low temperature drift for the circuit. This circuit provides all the typical voltage and current output ranges with 16-bit resolution and no missing codes, 0.05% linearity, and less than 0.2% total output error.
