... Instruction, and Data Bytes again. Similarly, a repeated Read function of the RDAC is also allowed. MULTIPLE DEVICES ON ONE BUS Figure 5 shows four AD5282 devices on the same serial bus. Each has a different slave address sine the state of their AD0 and AD1 pins are different. This allows each RDAC within each device to be written to or read from independently ...
