This circuit shows how to make a bipolar output 12-bit
DAC with a wide output swing using an LTC1451 and an
LT1077. R1 and R2 resistively divide down the LTC1451
output and an offset is summed in using the LTC1451
onboard 2.048V reference and R3 and R4. R5 ensures that

the onboard reference is always sourcing current and
never has to sink any current even when V
scale. The LT1077 output will have a wide bipolar output
swing of – 4.096V to 4.094V as shown in the figure above.
With this output swing 1LSB = 2mV.
