re analog switches balan michael fulbright said analog switches balanced to all on mf i am trying to build a synchronous demodulator and i ve hit a snag mf in my application i want to be able to change the gain of an mf op amp amplifier from to controlable via a digital input mf the most obvious way i ve come up with is to use analog switches mf to adjust the gain of the op amp the only analog switch i have mf experience with it the unfortunately i want to switch an mf ac signal which goes from about v to v and the is only mf for positive signals how about using a it has a seperate ground for the analog outputs it would get you bits mf another part which caught my eye was the analog devices ad this mf is a balanced demodulator which appears to fill exactly the need i mf have the data sheet was somewhat skimpy on application notes could mf someone comment on using this chip for the following application or how about a multiplying d a convertor this is essentiallty what you are makeing stephen cyberman toz buffalo ny us mangled on fri at catch the blue wave blue wave qwk v
