8.1 Application Information

The application circuit shown in Figure 20 is an AC mains-line driver over 40-kHz-to-90-kHz utility band and is based around the European standard (EN56065–1) describing utility and consumer applications. This example shows a possible implementation for differential transmission on the mains line. This applications circuit is designed around the requirements of a domestic electricity meter operating over a utility band of 40 kHz to 90 kHz.
