... Programmable Voltage and Current Sources Programmable Attenuators GENERAL DESCRIPTION The AD5310 is a single, 10-bit buffered voltage out DAC that operates from a single +2 +5.5 V supply consuming 115 Its on-chip precision output amplifier allows rail- to-rail output swing to be achieved. The AD5310 utilizes a ver- satile three-wire serial interface that operates at clock rates MHz and is compatible with standard SPI™ ...

... 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 AD5310 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 ...

... Hex) is loaded to the DAC register. Ideally the output should The zero-code error is always positive in the AD5310 because the output of the DAC cannot go below due to a combination of the offset errors in the DAC and output amplifier. Zero-code error is expressed in mV. A plot of zero-code error vs ...

... DIN line is clocked into the 16-bit shift register on the falling edge of SCLK. The serial clock frequency can be as high as 30 MHz making the AD5310 compatible with high speed DSPs. On the sixteenth falling clock edge, the last data bit is clocked in and the programmed function is executed (i.e., a change in DAC register contents and/or a change in the mode of operation) ...

... AD5310. If the low DIN dropout REF195 is used, the current which it needs to supply to the AD5310 is 140 A. This is with no load on the output of the DAC. When the DAC output is loaded, the REF195 also needs to supply the current to the load. The total current required (with load on the DAC output) is: 140 V ...
