 | Kit Overview
The circuit EVAL-CN0202-SDPZEVAL-CN0202-SDPZ Evaluation board provides a full function, flexible, programmable analog output solution that meets most requirements for programmable logic controller (PLC) and distributed control system (DCS) applications. The AD5662AD5662 low power (0.75 mW @ 5 V), rail-to-rail output, 16-bit nanoDAC
The ADR444ADR444 low drift (3 ppm/°C 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 AD5750AD5750 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.
The circuit also contains key features for industrial applications, such as on-chip output fault detection and protection (short circuit, undervoltage output, open circuit current output, and overtemperature), CRC checking to prevent packet error (PEC), and flexible power-up options, making it an ideal choice for robust industrial control systems. No external precision resistors or calibration routines are needed to maintain consistent performance in mass production, thereby making it ideal for PLC or DCS modules.
The CN0202 Circuit requires the SDP-B controller board for connection to the PC and runing the Analog Devices evaluation software. The SDP-B controller board used for data transfer from evaluation board to PC via USB interface. It does not come as part of the evaluation kit and can be ordered separately (EVAL-SDP-CB1ZEVAL-SDP-CB1Z). It can be reused with many other Analog Devices evaluation modules.
