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…

Has anyone had success with this chip?

I'm experiencing really bad crosstalk between the two inputs. input 2 audio coming through to input 1 side.

Can anyone help on this?

The video is perfect... just the audio that's causing a problem!

Hello.

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…

Hello,

I was wondering if Analog (incl. Maxim) offered more NMOS type switches like the ADG774A and ADG794.

I think the purely N-type switches would be way superior to the CMOS switches in many applications that do not require the full voltage range from…

Hi,  

When I measured the switch-off leakage current of the ADG709, I found that the value was incorrect. The test connection diagram is shown in the figure. Why is the leakage current of the test much larger than the standard maximum value of 20nA in the…

Hello everyone

In my project I have to build an LVDT including its signal conditioner circuit. I have recently found on the internet that one can build an LVDT using  a very inexpensive signal conditioner circuit which includes components such as ADA2200…

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…

Hello all,

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…
