Where do I tie the exposed paddle on DACs such as the AD5541A, AD5542A, AD5512A, AD5668, AD5628, AD5669 and AD5629 that are packaged in LFCSP?

你好，我看AD8628的文档说AD8628是单电源供电，但是在AD5512A的文档里，说AD5512A的双极性输出操作是，给出的例子里用的就是AD8628，但是图里面是接的确实双电源，如下图

我使用的AD5512A的双极性输出，那应该是5v单电源，还是双电源+-5V？谢谢

Dear AD engineers,

Could I ask if +5V/-5V is supported for AD5542A in bipolar mode? It is specified in datasheet everywhere that a 2.5V reference should be used, such as in page 8: Pin REF Connect this pin to an external 2.5 V reference.

Thanks a lot…

Around 256K data is stored as a bunch in memory and we need to convert this digital data to analog at once by applying it to AD5542A dac ic. As chip select need to go low to high after each 16 bit data to latch it to dac.

AD5398, 120mA Current sinking DAC With Reduced Current Range

I'm working with the AD5398. I don't need the full 120mA range of the device.  Is it possible to get the full 10bit resolution over a smaller current range, say 20mA?   What would be the…
