![]() | Kit Overview
The circuit EVAL-CN0229-SDPZEVAL-CN0229-SDPZ is a multichannel, flexible, analog output solution with only two analog components and meets most requirements for multichannel I/O cards, programmable logic controllers (PLCs), and distributed control systems (DCSs) applications. The AD5686RAD5686R quad, 16-bit nanoDAC+ with rail-to-rail buffered outputs combined with four of the AD5750-2AD5750-2 industrial current/voltage output drivers provide all the typical output current and voltage ranges with 16-bit resolution, no missing codes, 0.05% linearity, and less than 0.1% output error.
An ultralow drift (2 ppm/°C typical), 2.5 V voltage reference with high drive capability (up to ±5 mA) is integrated in the AD5686RAD5686R and provides the reference voltage for both the AD5686R and the AD5750-2. This guarantees low noise, high accuracy, and low temperature drift for the circuit.
The ADuM1301ADuM1301 and ADuM5400ADuM5400 provide 2500 V rms isolation both on power, and all the necessary signals between the analog signal chain and the host controller.
For multichannel I/O card applications that need more than 4 channels, several AD5686RAD5686Rs can be connected in a daisy chain, and no additional external digital I/O circuits are required. This minimizes the cost, especially for high channel count isolated applications.
The circuit also contains key features for industrial applications, such as on-chip output fault detection, packet error checking (PEC) by the CRC, flexible power-up options, and ESD protection (4 kV for the AD5686RAD5686R, human body model and 3 kV for the AD5750-2AD5750-2, human body model), 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.
This circuit uses the EVAL-CN0229-SDPZEVAL-CN0229-SDPZ circuit board and the EVAL-SDP-CB1ZEVAL-SDP-CB1Z System Demonstration Platform (SDP-B) evaluation board. The EVAL-CN0229-SDPZEVAL-CN0229-SDPZ board contains the circuit to be evaluated and the SDP evaluation board is used with the CN-0229 evaluation software to capture the data from the EVAL-CN0229-SDPZEVAL-CN0229-SDPZ circuit board.
