1.2.3
Table 4 illustrates the power supply connections to the evaluation board. The +5 binding post (J3) supplies the pos-
itive analog (VA+) for the CS5461A and the +2.5V reference. The VD+_EXT binding post (J5) supplies the digital
section of the CS5461A (VD+) and level shifters. Jumper J8 allows the VD+ supply to be sourced from the VD+_EXT
binding post (J5), the +5V binding post (J3), or the regulated 3.3V supply derived from the microcontroller. The
Vu+_EXT (J6) binding post supplies the positive supply for the 8051 microcontroller (8051_REGIN). Jumper J9 al-
lows the 8051_REGIN supply to be sourced from either the Vu+_EXT binding post (J6), +5V binding post (J3) or
VD+_EXT binding post (J5).
