... The asynchronous CLR function can be configured to clear the output to minus full-scale or midscale depending on the state of Pin 17 when CLR is strobed. The AD760 also powers up with the REV. A Information furnished by Analog Devices is believed to be accurate and reliable. However, no responsibility is assumed by Analog Devices for its use, nor for any infringements of patents or other rights of third parties which may result from its use ...

... DAC Gain Error is measured without the on-chip voltage reference. It represents the performance that can be obtained with an external precision reference. 7 External current is defined as the current available in addition to that supplied to REF IN and SPAN/BIPOLAR OFFSET on the AD760. 8 Operation on ±12 V supplies is possible using an external reference such as the AD586 and reducing the output range. Refer to the Internal/External Reference section ...

... ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the AD760 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality ...

... Internal scaling resistors provided in the AD760 may be con- nected to produce a unipolar output range + bipolar output range of – +10 V. Gain and offset drift are minimized in the AD760 because of the thermal tracking of the scaling resistors with other device components. REV. A ...

... V to +10.24 V. For example, by using the AD586 5 V reference, outputs ±5 V can be realized. Using the AD586 voltage refer- ence makes it possible to operate the AD760 with ±12 V sup- plies with 10% tolerances. Figure 7 shows the AD760 using the AD586 precision 5 V refer- ence in the bipolar configuration. The highest grade AD586MN is specified with a drift of 2 ppm/° ...

... D-to-A Glitch Impulse Figure 8. Output Characteristics DIGITAL CIRCUIT DETAILS The AD760 has several “dual-use” pins that allow flexible op- eration while maintaining the lowest possible pin count and con- sequently the smallest package size. The following information is useful when applying the AD760. ...

... Figure 11. The MOSI, SCK, and SS pins of the HC11 are respectively connected to the S pins of the AD760. The majority of the interfacing issues are taken care of in the software initialization. A typical routine such as the one shown below begins by initializing the state of the various SPI data and control registers ...
