SETTING UP THE EVALUATION BOARD
Figure 2 shows the simplified EVAL-ADAQ8088EBZ block
diagram. The ADAQ8088 μModule that is soldered to the
EVAL-ADAQ8088EBZ requires a supply voltage from 2.7 V to
3.3 V. The EVAL-ADAQ8088EBZ allows the user to set the
I_OUT_V
OCM
pin and Q_OUT_V
OCM
pin of the EVAL-
ADAQ8088EBZ through the EXVCMA and EXVCMB jumpers.
ANALOG INPUTS
The EVAL-ADAQ8088EBZ I inputs (I_INP and I_INN) are
connected through the J1 and J2 SMA connectors, respectively,
and the Q inputs (Q_INP and Q_INN) are connected through
the J4 and J3 SMA connectors, respectively.
