5-1 Initial Setup of the Board
Initial Setup of the Board
Factory set up of the board is for a
±
5-V to
±
12-V analog front-end supply at
J7, and 5-V ADC power provided through J8. The BV
DD
supply is provided
from the DSK platform via J11 and W18 (pins 2 and 3 shorted). The maximum
analog inputs are 0-V/5-V for a differential signal. The reference circuit is
connected to the internal reference of the ADC (W13 pins 2 and 3 shorted).

The analog inputs to the ADS8364EVM board can be applied to any one or all
of the input channels. Single-ended inputs are to be applied between analog
ground (center terminal of J1–J6) and either the positive or negative terminals.
Differential signals are to be applied between the positive and negative
terminals.
