Fig.12 Application diagram for differential input mode using an input transformer.

The analog, digital and output supplies should be separated and decoupled.

(1) Differential clock signals can be applied if required.

(2) R1 and R2 must be determined in order to obtain 3.4 V at the transformer; see Table 1.

Adaptation with the single input signal impedance must be taken care of.
