44 / 93 page  Data Sheet ADFS7124-8 GETTING STARTED analog.com Rev. 0 | 44 of 93 Understanding Configuration Flexibility In Figure 70, Figure 71, and Figure 72, the registers shown in black font are programmed for this configuration. The registers shown in gray font are redundant. The most straightforward implementation of the ADFS7124-8 is to use differential inputs with adjacent analog inputs and run all of them with the same setup, gain correction, and offset correction register. For example, for four differential inputs, select the following differential inputs: AIN0/AIN1, AIN2/AIN3, AIN4/AIN5, and AIN6/ AIN7. Programming the gain and offset registers is optional for any use case, as indicated by the dashed lines between the register blocks. If an internal or system offset or full-scale calibration is performed, the gain and offset registers for the selected channel are automati- cally updated. An alternative way to implement these four fully differential inputs is by taking advantage of the eight available setups. Motivation for this includes having a different speed, noise, or gain requirement on some of the four differential inputs vs. other inputs, or there may be a specific offset or gain correction for particular channels. Figure 71 shows how each of the differential inputs can use a separate setup, allowing full flexibility in the configuration of each channel.
