Hi all:
I'm using the Filter Wizard tool: Filter Wizard | Analog Devices to design a high pass filter, my amp is single power supplied, and the wizard adds a reference voltage generation circuit using AD8031.
Click "What's this" and it says:
Can I use other opamp instead of AD8031? I want to use AD8039 or AD8034, they have 2 opamps in one package, and can work with higher supply voltage.
Thanks!
Not many op amps will tolerate high value capacitors without oscillating. We have used the AD8031
in many designs. You will have to test any other op amp that you want to use.
