JAJSIU8B June 2015 – April 2020 ADS131E08S
Figure 70 shows an example layout of the ADS131E08S requiring a minimum of two PCB layers. The example circuit is shown for either a unipolar analog supply connection or a bipolar analog supply connection. In this example, polygon pours are used as supply connections around the device. If a three- or four-layer PCB is used, the additional inner layers can be dedicated to route power traces. The PCB is partitioned with analog signals routed from the left, digital signals routed to the right, and power routed above and below the device.
