#104880 - do you remember the math in a previous p Responding to: ???'s previous message |
Erik , how do you manage to provide Analog Vcc for Analog side of your circuits? As i said in previous post(Circuit H) i have been using RC filters.But if Analog section includes a Op-Amp it could draw up to 10mA.Is it alright to use a RC filter here?
do you remember the math in a previous post: 10mOhm and 10mA gives a drop of 100 uV HOWEVER "Circuit H" is seriously flawed a) both 12V in and 12V out is labelled Vcc and b) there is no indication that the voltage, which you now tell is analog supply, is stabilized. If you drive analog circuitry from a non-stabilized voltage, filtering will be the least of your problems. Erik |
