Function
These links connect the input of V
V
potentiometer.
These links connect the power supply pins of the operational amplifiers to 3.6 V regulated output from the
on-board ADP3330 voltage regulators, or to 5 V supply from J1.
These links tie the operational amplifiers to the analog inputs of the AD7997/AD7998.
LK7 selects the power source for V
LK8 changes the value of the external reference voltage (AD780).
LK9 changes the source of the reference voltage for the AD7997/AD7998.
LK15 connects the input of V
sensor.
IN
In Position A, an operational amplifier is supplied from J1.
In Position B, an operational amplifier is supplied from the ADP3330.
In Position A, the operational amplifier is used.
In Position B, the operational amplifier is not used.
In Position A, LK7 selects the 5 V supply from the USB connector.
In Position B, LK7 selects the 3.3 V regulated output from the on-board ADP3303 voltage regulator.
If this link is inserted, the reference voltage is 3 V.
If this link is not inserted, the reference voltage is 2.5 V.
In Position A, an external reference source is used (AD780).
In Position B, the 5 V supply from J1 is used as a reference voltage.
