Nastase Fri, 15 Oct 2010 06:01:40 +0000 http://masteringelectronicsdesign.com/?p=300#comment-2767 An ideal differential amplifier can be represented by an ideal dependent voltage source. It is dependent, because its value is given by the product between the differential input voltage and the amplifier gain. So, here you go, you have a voltage source connected to a load (you say loaded amplifier) and this voltage source is probably part of a circuit. Then you can apply Thevenin's Theorem to solve the circuit. If you need more details, you need to tell me more. Maybe send me a schematic?

There is plenty of info here. Thank you. I am also looking forward for an answer to the questions you posted at the end.

Looking forward for the next ones, especially the temperature coefficient influence on the circuit precision. These are great posts about the differential amplifier.
