supply.
A single +5.0 V DC supply for analog section of the board (A/D + Refer-
ence).
A single +5.0 V or +3.3 VDC supply for digital section of the board (A/D +
address decoder + buffers).
There are two ways to provide these voltages.
1)
Wire in the voltages at test points on the EVM. See Table 41.

Description
TP16
+BVDD
Apply +3.3 V or +5.0 V. See ADC datasheet for full range.
TP20
+AVCC
Apply +5.0 V.
TP14
+VA
Apply +6.0 V. Positive supply for amplifier.
TP18
VA
Apply –6.0 V. Negative supply for amplifier.
2)
Use the power connector J1, and derive the voltages elsewhere. The
pinout for this connector is shown below. If using this connector, set W4
jumper to connect +3.3 V or +5 V from connector to +BVDD. Short
between pins 12 to select +5 VD, or short between pins 23 to select
+3.3 VD as the source for the digital buffer voltage supply (+BVDD).
