Specifications of AD8191-EVAL

• Lead Free Status / RoHS Status: Contains lead / RoHS non-compliant

In applications where the AD8191 is powered by a single 3.3 V
supply, it is recommended to use two reference supply planes
and bypass the 3.3 V reference plane to the ground reference
plane with one 220 pF, one 1000 pF, two 0.01 μF, and one 4.7 μF
capacitors. The capacitors should via down directly to the
supply planes and be placed within a few centimeters of the
AD8191. The AMUXVCC supply does not require additional
bypassing. This bypassing scheme is illustrated in Figure 34.
