Hi,
I would like to know the internal impedance of the TLV803S from the VDD pin.
The specfication sheet of TLV803S has a diagram of R1R2.
But its value is not marked anywhere.
I measured the VDD impedance of the AAS322 using a calibrated measuring instrument.
The results suggest an impedance of more than megohms.
The IDD supply current value is written as TYP 9uA~ on the specfication sheet, but the actual measurement results were very much smaller than that.
This suggests that R1R2 has a higher resistance value than megohms.
1. What is the value of R1R2?
2. Is the internal impedance seen from the VDD pin considered high impedance?
BR,
Yuta Doi
