Typical Interface Circuit

Very few external components are required to achieve

the stated device performance. Figure 3 shows the typical

interface requirements when using the CDK1301 in nor-

mal circuit operation. The following sections provide

descriptions of the major functions and outline performance

criteria to consider for achieving the optimal device

performance.

Analog Input

The input of the CDK1301 can be configured in various

ways depending on whether a single-ended or differential

input is desired.

The AC-coupled input is most conveniently implemented

using a transformer with a center-tapped secondary winding.
