3. Typical Connection Diagrams
Figures 1 and 2 illustrate the typical connection diagram for the CS5333 and CS5340 respectively. The
analog and digital core of the CS5333 are powered from VA, which can be set from 1.8 V to 3.3 V. The
VL supply pin powers the digital interface logic from 1.8 V to 3.3 V and can be set independently from VA.
