NOTES:
1. The transformer is design to provide isolation from the AC line voltage to 2.From the AC Voltage line, a resistor divider, R1 and R2, can be used to
an IC with a high input impedance, and minimum phase shift. The output step the voltage down to below the maximum input voltage.
sine wave will not be distorted if the input voltage does not exceed the
3.For R1, multiple lower value resistors can be used in series to reduce the
maximum rating.
