See TYPICAL APPLICATIONS when selecting the value of RSH.

Resistor (R1and R2) values are dependant upon the selected value of

RSH.

Capacitor (C9) to be positioned as close to Supply Pins (VDD & VSS) of IC-1,

as possible.

Capacitor (C11) selected for DC blocking and to minimize phase error

introduced by current transformer (typically 1.5µF).
