Function
Selects the common mode source, which is applied to the operational driving amplifiers. The
AD7766/66-1/66-2, inputs must be driven differentially using a common mode voltage of V
the EVAL-AD7766/66-1/66-2EDZ V
Allows the user to supply the common mode voltage from the 2.5V star point created at the 2.5V
DVDD supply. In this case, eliminate the two potential dividers (R9 & R11) and (R10 & R12) which are
set by default on the AD7766/-1/-2 board. Also ensure that the resistive link R39 (underside of the
PCB) is shorted.
Selects the 5V output of the ADP3330-5 device (U10).
Allows the user to apply an external common mode voltage using the SMB connector (J15) marked
“EXT_CMODE.
Setting the link to position, D allows the user to take the common mode for the ADA4841-1
amplifiers directly from the reference supply (output of U5, either ADR425 of ADR445). For this,
option short across the unpopulated resistor R34.
