SETTING OUTPUT VOLTAGE
The following diagrams show the connections used to set the output voltage.
Because the power supply to the error amps is provided by the same reference voltage circuit used for the other
internal circuits, the common-mode input voltage range is set at 1.05 V to 1.45 V.
The reference voltage input to the +IN and -IN pins should be set at 1.25 V (V
REF
/2). The method of connection
for channel 1 is different from channel 2 and channel 3. In addition, channel 1 is capable of picking up both
positive and negative voltages, while channel 2 and channel 3 can pick up only positive output voltages.
