Figure 5 Application circuit example
S8745-01 and S8746-01 use a package with the guard ring effect provided. To make it effective during measurement, the
package leads (pin 5 for S8745-01; pins 5 and 11 for S8746-01) should be connected to the ground line.
When a feedback resistor is externally connected, it is necessary to provide a guard ring on the circuit board or to provide a teflon
standoff for the leads.
Note) A tantalum or ceramic capacitor of 0.1 to 10 µF must be connected to the supply voltage leads (pins 3 and 9 for S8745-01;
pins 1 and 4 for S8746-01) as a bypass capacitor used to prevent the device from oscillation.
