Table 4
plies the positive analog (VA+) for the CS5467 and the +2.5V reference. The VD+_EXT binding post (J5)
supplies the digital section of the CS5467 (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 allows 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).
