BIPOLAR OPERATION
Bipolar operation is achievable using the MCP4725 by
using an external operational amplifier (op amp). This
allows a general purpose DAC, with its cost and
availability advantages, to meet almost any desired
output voltage range, power and noise performance.
Example 8-3 illustrates a simple bipolar voltage source
configuration. R1 and R2 allow the gain to be selected,
while R3 and R4 shift the DAC's output to a selected
offset. Note that R4 can be tied to VDD (= VREF) instead
of VSS, if a higher offset is desired. Note that a pull-up
to VDD could be used, instead of R4, if a higher offset is
desired.
