Hello

I have a problem with ADG1408

For input voltage 1Vpp I have 60mVpp at the output. Signal frequency is set to 1.25MHz. When I set signal frequency to 1kHz 1Vpp, the output signal is 900mVpp. But in datasheet (figure 22) I can read the bandwidth…

I used ADG1408 in the device which switches three differential inputs between 12 differential outputs (four channels for each input). In this way there are 6 ADG1408 chips and I use 4 output channels of each one, while remaining 4 channels are left unconnected…

Hi. I have a questions on ADG1408.

From page 9 of data sheet, "Overvoltages at A,EN,S or D are clamped by internal diodes..."

In inputs S the overvoltage protection are before (left in Figure 1 page1of data sheet) or after (right) the switches…

Customer has seen two parts fail in their system i.e. bubble on top. We are wondering if there is a power initiation sequence that should happen because of the dual rails. Is there any other thing you think could cause this?

        Hello, I have a problem  of ADG1408.

        Can I input 30V（respect to GND）voltage in drain of source while ±15V power supply by using ADG1408？ 

Are there some parameters I can change in the models for the ADG408/ADG409 parts to match how an ADG1408/ADG1409 would operate?

I have both spice models downloaded: AGD408/ADG409

I would like to simulate ADG1408/ADG1409

Thanks.

Hello,

The data sheet indicates max input supply of 25V.  Even though the device is only specified at +12V and +/-15V (and +/-5V), can it be safely powered single-supply at +24V?

If this is not advisable, is there an option for a low Rds 8:1 mux that…

Hi,

I'm working on a prototype which is using a total of 64 MUX controlled by FPGAs. MUX are powered with +/-12V. I started with assembling one MUX and tested it with success, I could easily control all switches. I then added 3 more MUX. What I observed…

Hi

I need a simulation model for ADG1408 (lower RON). I have the model for an ADG408.

Can anyone help with changing RON?
