Forum Post: RE: ADS7809 oscillation, "CAP" pin capacitor, low ESR?
Hi Ken,You are correct. The inherently higher ESR of the Tantalum cap works like an isolation resistor and helps keep the internal opamp stable. If you're using a ceramic cap instead, a 1ohm series...

Hi Jiri,If you apply 4kV to the supply, you will need extra protection for U20 as it is limited to 3kV isolation.You may find that you will have better success if AGND and DGND have a low impedance...
