I need to switch a differential analog signal with a common-mode voltage of 3.5 volts (output from an LTC5585 IQ demodulator) with at least 300 MHz of signal bandwidth into various gain stages and bandwidth-limiting filters, 25 to 250 MHz . The ADG794…
You should verify how much of the audio is coming through, the switch is specified with a 70dB of isolation, so it's possible to hear some of that but it should be at a much much lover level. Can you measure and quantify the cross talk?
If its more…
I'm trying to synchronously rectify and integrate a high-impedance AC signal using an ADG794 switch in the circuit shown below.
It works for lower values of R1, but once the current drops below about 100nA RMS, the integrator goes the wrong…
Were you able to resolve this?
I am planning to do the exact same thing.
I am unable to understand whether I need to have 8 ADA2200 devices or 8 ADG794 switches!
Can you please share some starters?
Hello!Recently I saw the board of CN-0371, but I have a doubt, because the LVDT matched with CN0371 is driven by square wave excitation signal, so the existence of ADG794 is meaningful, but I want to use MHR-050LVDT, which is driven by sine wave excitation…
I am using the reference design in as described in CN0371 where in an ADA2200 is driving an ADG794 switch. The the reference has 2 of the four outputs of the switch dedicated to driving P+ and 2 dedicated to P-.
So here is my question: I need…
Did you checked these:
And some selected parts:
