Chapter 005, Analog Control System Design


In addition, the reference output voltage of the ADR is 2. The ADuM is a triple-channel digital isolator.

The ADuM is a quad-channel digital isolator with an integrated, isolated, dc-to-dc converter. Construct the circuit on a multilayer printed circuit board PCB board with a large area ground plane.

The AD has highly flexible and configurable output ranges that can be tailored to meet the needs of the application. The AD range was set for 0 V to 5 V. The test results for all the other ranges are listed in Table 1. Note that the output ranges 3. There is a lower dead band about 10 mV referenced to GND. All the linearity test results were calculated using a reduced code range of to 65, The AD can accept 0 V to 4.

The AD can accept a 0 V to 2. Using My Computer , locate the drive that contains the evaluation software CD and open the Readme file. Follow the instructions contained in the Readme file for installing and using the evaluation software. Figure 5 shows a functional block diagram of the test setup. Test Setup Functional Block Diagram. An automatic test program is necessary to step through the codes and analyze the data.

This is not provided on the CD but must be implemented by the customer to correspond to the requirements of the particular multimeter used in the test setup. This allows the multimeter readings corresponding to each code to be loaded into an Excel spreadsheet in the PC.

The AD is a single channel, low cost, low power, rail-to-rail voltage buffered output nano DAC device. The whole system will benefit from the ultralow noise and low temperature coefficient of the ADR The ADR44x family of references are ideal for driving either the reference or the power input of converters because they can source and sink current. The AD also incorporates a power-on reset circuit to ensure that the DAC output powers up to either midscale or zero and remains there until a valid write takes place.

The ADuM is a triple channel digital isolator. They are used to provide isolation between the signal chain and the system microcontroller, with an isolation rating of 2. The ADuM provides an isolated 5 V power supply for all the circuit in the secondary side.

Features & Benefits

Nylon hardware should be used to firmly secure the two boards, using the holes provided at the ends of the pin connectors. This circuit provides all the typical voltage and current output ranges with bit resolution and no missing codes, 0. The AD has highly flexible and configurable output ranges that can be tailored to meet the needs of the application. This result is used with the results of other rules to finally generate the crisp composite output. Fuzzy logic is widely used in machine control.

The digital power and analog power should be separated and connected with a ferrite bead. See the schematics in the CN Design Support package for more details. The AD has integrated ESD protection diodes internal to each pin that can prevent damage from transients.

The circuit must be constructed on a multilayer PC board with a large area ground plane. The AD has highly flexible and configurable output ranges that can be tailored to meet the needs of the application. The AD range was set for 0 V to 5 V. The test results for all the other ranges are listed in Table 1.

Note that the output ranges 0 mA to Using "My Computer," locate the drive that contains the evaluation software disc and open the Readme file. Follow the instructions contained in the Readme file for installing and using the evaluation software.
