■ ABOUT ADJUSTMENT OF VTH
■ ADJUSTMENT OF VTH
- 4 -
Adjustment method is as following.
The switch threshold voltage ( Vth ) is possible to adjust by external parts to SW C/SW R.It needs to be satisfy with
condition of Vth≤V
This reason is cased by equivalent circuit of comparator for switch.
The Vth has to be adjust in case that supply voltage is less than 5V (
In case of Ii=100µA,Ri=25kΩ
● Internal Vth ( Single supply )
● Vth,2.5V ( Single supply )

-2V.
,Re ( External Resistor )

● Vth>2.5V ( Single supply )
±2.5V ).
