The analog and digital supplies should be separated and decoupled.
(1) Clamp capacitors must be determined in accordance with the application; recommended values are CLPY = 18 nF, CLPU and CLPV = 33 nF.
(2) It is possible to use the reference output voltage pin SDN to drive other analog circuits under the limits indicated in Chapter “Characteristics”.
(3) Input signal pins have a high bandwidth. It is necessary to take special care on PCB layout to avoid any interaction from other signals (digital clocks
for example).
