We do not have a device that is pin for pin compatible with the ADG707 that has no clamping diodes on the input pins. An option could be to use the ADG5209F. The ADG5209F has no clamping diodes on the input and can block a DC voltage when there are…
Once Vdd is removed all the switches will be off.
Just out of interest have you had a look at the newer versions of these devices the ADG5209F or the ADG5249F?
Our latest overvoltage protection multiplexers are the ADG52XXF family. The ADG5209F or the ADG5249F are both differential 4:1 devices and are the highest density devices we currently have.
These devices are available in a 4 mm x 4 mm LFCSP package…
This sounds like it could be caused by charge coupling or charge injection.
See MT-088 for explanation of these effects.
Have you looked at the ADG52xxF family. depending on your application you may be able to use an ADG5209F (this is a Dual 4:1…
When the ADG5206 is un-powered we are unable to guarantee whether the switch is on or off. If a 5V DC signal is applied to the device when it is powered off, then the diode to VDD on the input of the switch will become forward biased and current…
Q1. What are the key benefits of these fault protected switches?
A1. There are a number of key features on these parts
