I want to do Signal Integrity simulation with AD8139, but I can't find the IBIS file of AD8139. Does ADI offer its IBIS file? If not, could I do the Signal Integrity simulation in other way? Thank you.
I am trying to measure noise voltage spectral density and I found that simulation result is way off the mark from the value of 2.25 nV/sqrt(Hz) which datasheet has given. I tried simulate it in pspice and multisim independently and the result was the…
What's the recommended input OVP of AD8139, say the input voltage may go to 20Vpp, and +/-5V power supply? If I can use input series resistor to limit the input current in OVP situation? If it work, what's the maximum input current which AD8139 can afford…
Hello,
I am interested in using the AD8139 as an RF-switch driver since it's supposed to get <11ns switching speeds. The design is detailed here: www.edn.com/contents/images/10605di.pdf
I am trying to get the swing as close to 0V and -5V as possible…
I,m a young application engineer for LXT-Credence company.
I have design for a customer who wants to test infra red sensor, a loadboard.
As the sensor delivers an output analog signal, and contains 288x384 pixels, I decided to use an ADC to…
Dear Sir/Madam,
I wonder knowing the abnormal area of below figure, why it is not flat.
thanks.
现想用Cadence做PCB的的SI仿真，但是AD8139没有IBIS仿真模型，只有SPICE模型，请问利用SPICE模型能不能进行PCB的SI仿真？谢谢！analogchina-adminhdx2FormerMemberAnalog1ezchinatest1122engineerzone.adminezchinatest1122
I am using the AD8139 in the as shown in the attached PDF.
Spice simulations work fine. But On the bench using +-5V supplys, AD8138 outputs Nothing.
What did I do wrong.

Software can't apply 5 volts and -5 volts to the AD8139 driver on my board. They tell me that one could be applied as much as one second after the other. Could this cause latchup? I just wanted to start the conversation. I can provide schematics if…
