... AD5530/AD5531 TERMINOLOGY Relative Accuracy Relative accuracy or endpoint linearity is a measure of the maximum deviation, in LSBs, from a straight line passing through the endpoints of the DAC transfer function. Differential Nonlinearity Differential nonlinearity is the difference between the measured change and the ideal 1 LSB change between any two adjacent codes. A specified differential nonlinearity of ± ...

... THEORY OF OPERATION DAC ARCHITECTURE The AD5530/AD5531 are pin-compatible 12- and 14-bit DACs. The AD5530 consists of a straight 12-bit R-2R voltage mode DAC, and the AD5531 consists of a 14-bit R-2R section. Using reference connected to the REFIN pin and REFAGND tied bipolar ±10 V voltage output results. The DAC coding is straight binary ...

... D is the decimal data-word loaded to the DAC register the resolution of the DAC. BIPOLAR CONFIGURATION Figure 21 shows the AD5530/AD5531 in a bipolar circuit configuration. REFIN is driven by the AD586 reference, and the REFAGND and DUTGND pins are tied to GND. This results in a bipolar output voltage ranging from − +10 V. ...

... ADDITIONAL PINS OMITTED FOR CLARITY. Figure 23. AD5530/AD5531 to ADSP-21xx Interface AD5530/AD5531 TO 8051 INTERFACE A serial interface between the AD5530/AD5531 and the 8051 is shown in Figure 24. TxD of the 8051 drives SCLK of the AD5530/AD5531, while RxD drives the serial data line, SDIN. P3.3 and P3.4 are bit-programmable pins on the serial port and are used to drive SYNC and LDAC , respectively ...

... AD5530/AD5531 LDAC is controlled by the PC6 port output. The DAC can be updated after each 2-byte transfer by bringing LDAC low. This example does not show other serial lines for the DAC. If CLR were used, it could be controlled by port output PC5. To read data back from the DAC register, the SDO line can be ...

... In many process control applications necessary to provide an isolation barrier between the controller and the unit being controlled. Opto-isolators can provide voltage isolation in excess of 3 kV. The serial loading structure of the AD5530/ AD5531 makes it ideal for opto-isolated interfaces because the number of interface lines is kept to a minimum. ...
