Initial Board Setup
Initial Board Setup
Factory setup of the board is for a 5-V analog and digital power supply. The
socketed OP2350A is a rail-to-rail operational amplifier. The maximum analog
input signals are 0-V to 5-V differential. The reference circuit is connected to
the internal reference of the ADC (JP11 Closed) (refer to Table 4
1).

The analog inputs to the DEM-ADS7864 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.
