Typical applications involving transformer coupled circuits are discussed in this section. Transformers (such as ADT1-1WT or WBC1-1) can be used up to 250 MHz to achieve good phase and amplitude balances at ADC inputs. While designing the dc driving circuits, the ADC input impedance must be considered. Figure 83 and Figure 84 show the impedance (Zin = Rin || Cin) across the ADC input pins.
