CN0204 Evaluation Board Guide
Overview
CN0204 is 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. It 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. Furthermore, it also contains key features for industrial applications, such as on-chip output fault detection, 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 AD5751 is a single channel, low cost, precision voltage/ current output driver developed to meet the requirements of industrial process control applications. The AD5751 is specified to operate with a power supply range from 10.8 V to 55 V, and the voltage output can be up to 44 V. The voltage output range can be programmed for the standard output ranges and 20% overrange settings for PLC and DCS applications: 0 V to 5 V, 0 V to 10 V, 0 V to 6 V, 0 V to 12 V. In addition, two high voltage output ranges are also provided: 0 V to 40 V and 0 V to 44 V. The current output, which is provided on a separate pin, can be programmed for the standard ranges of 4 mA to 20 mA, 0 mA to 20 mA, 0 mA to 24 mA. There is also a 2% overrange setting which provides 3.92 mA to 20.4 mA, 0 mA to 20.4 mA, and 0 mA to 24.5 mA. The voltage and current output pins can be tied together to configure the end system as a single-channel output if desired.
The AD5662 is a low power (0.75 mW typical @ 5 V), rail-to-rail output, 16-bit nanoDAC® device. The AD5662 guarantees ±1 LSB DNL under a wide range of reference voltages that can vary from 0.75 V to the VDD supply. In the circuit of Figure 1, the AD5751 and AD5662 operate from a common reference source of 4.096 V, provided by the ADR444.
The ADuM1301 and ADuM5401 provide all the necessary signal isolation between the microcontroller and the analog signal chain. They are both based on the iCoupler® technology. Additionally, the ADuM5401 provides an isolated 5 V power supply for all the circuit in the secondary side.
Devices for PLC and DCS applications generally need ESD protection and overvoltage protection much higher than the formal recommended specifications. Thus, external 64 V, 1500 W transient voltage suppressors (TVS); a 50 mA, 30 V PolySwitch; and power Schottky diodes are built into the EVAL-CN0204-SDPZ circuit board to provide higher voltage ESD protection, 50 mA overcurrent, and 64 V overvoltage protection.
Required Equipment

General Setup
Block Assignments
- The EVAL-CN0204-SDPZ (CN0204 Board) connects to the EVAL-SDP-CB1Z (SDP-B Board) via the 120-Pin Connector (SDP CONN)
- The EVAL-SDP-CB1Z (SDP-B Board) connects to the PC via the USB cable
- Terminal block CN1 is the current output
- Terminal block CN2 is the +6 V power supply input
- Terminal block CN3 is the +/- 50 V power supply input
- Connect the +25 V power supply to the 12-50 VIN terminal
- Connect the -25 V power supply to the GND_ISO terminal
- Terminal block CN4 is the voltage output
- Optionally if JP3 is open, the output voltage feedback can be configured by connecting VSENSE+ to a selected node in the load circuit
Power on the (EVAL-CN0204-SDPZ) through the triple output power supply and the (SDP-B Board) through the PC SEPARATELY before connecting the two boards together.
Jumper Settings
See the table in the image below for the jumper settings. Values in red are the default settings for the EVAL-CN0204-SDPZ.
Installing the Evaluation Software
- Extract the file CN0204 Evaluation Software and open setup.exe
NOTE: It is recommended that you install the CN0204 Evaluation Software to the default directory path C:/Program Files (x86)/Analog Devices/CN0204/ and all National Instruments products to C:/Program Files/National Instruments/
- Press Next to view the installation review page
- Press Next to start the installation
- Upon completion of the installation of the CN0204 Evaluation Software, the installer for the ADI SDP Drivers will execute.
NOTE: It is recommended that you close all other applications before clicking “Next”. This will make it possible to update relevant system files without having to reboot your computer.
- Press Next to set the installation location for the SDP Drivers
It is recommended that you install the drivers to the default directory path
C:/Program Files/Analog Devices/SDP/Drivers
- Press Next to install the SDP Drivers. When prompted by Windows Security, just press Install
- Press Finish to complete the installation
