I know the ADG904 can handle a DC bias of 0.5V, however I'd like to clarify something: can the switch actually pass DC from one port to the common port?
E.g. if I inject 0.1V DC to RF1, will I get 0.1V DC on RFC?
Thank you for your help
i have a question about ADG904
i can't find information about turn on registance in datasheet.
can you tell me about turn on registance??
I am using the ADG904 in one of my designs, and am planning to control the switch (A0, A1 I/O) via signals I'm bringing onto the board through LVDS receivers.
The datasheet for the ADG904 specifies that the absolute maximum we can…
What is difference between ADG904 and ADG904-R evaluation boards?
The input of the circuit is a multiplexer ADG904.
It is protected by a specific protection system based on TVS to limit the lignthing waves which may subject the circuit.
The input level specified in the datasheet of ADG904 is very low.
Dear Sir/ Madam,
when I use ADG904, should i need connecnt another 50ohm resistor on the reciver board. And whether or not the ADG904 could operate bidirection.
I am facing problems to reply to you in my last post. Your answer was:
I think there are a few things to consider here in this crystal switching application. It sounds like your shunt load conditions for the TCXO are up to 10pF-10kohm (in parallel…
I have a technical question on ADG904 RF switch.
We wish to use it as analog switch for single frequency clipped sine-wave TCXO selection (from 10MHz to 100MHz).
The problem is that we can’t load the TCXO for more than 10pF + 10K ohm and therefore we…
Is there a spice model I can use for simulation?
Also, pls answer the specific question
why the switch will attenuate the sine-wave of the TCXO?
The ADG704 has 54pF ON capacitance and it might degrade signal of TCXO (limit of 10pF).
Sorry for repeating my question, I just don’t understand why the signal will be degraded – is the shunt transistors works when the switch is on?
