APPLICATIONS
Single Supply Operation:
The DG411, DG412, DG413 can be operated with unipolar
supplies from 5 V to 44 V. These devices are characterized
and tested for unipolar supply operation at 12 V to facilitate
the majority of applications. In single supply operation, V+ is
tied to V
vs. Supply Voltage curve for V
requirments.

Summing Amplifier
When driving a high impedance, high capacitance load such
as shown in figure 8, where the inputs to the summing
amplifier have some noise filtering, it is necessary to have
shunt switches for rapid discharge of the filter capacitor, thus
preventing offsets from occurring at the output.
