ALM-2712 module with differential output
A differential output can be implemented for the ALM-2712 using the schematic shown below. Suggested component
values are listed in Table 3. C1, C2 and L1, L2 are to convert the single-ended output to differential outputs while C3, C4
and L3 provide matching to 100 ohm differential impedance.
