We have data for +/-5V and + 5V operating condition .
Do you have details of the Spec details when used at +12 V .
With best regards and wishes
I am moving this thread to the amplifier community. Somebody will help you with your inquiry.
I contacted the product owner regarding this. I will get back to you once i have the information.
I am not able to post question in Amplifier area .
I have another question with regards to Enable / Disable function on AD8099.
Can we connect to controllers output open collector so that we can enable AD8099 for normal operation.
How to use the Enable / Disable with controller, is this possible .
Please let me know there is a reference circuit using Disable function .
[Enable Pin Leakage Current] Condition is DISABLE = 5 V in this condition the device will be Low Input Bias Current
With regards and wishes
We have only characterized AD8099 for +5 and +/-5V supplies. All the characterization data that we have is already in the datasheet. The +5V supply table should give you an idea on the performance of part at a +12V supply.
Yes, you can connect the controller directly to the DISABLE pin as long as you set the proper supply voltage level (please see Table 5 of the datasheet). You can have an option to disable or enable the part or reduce the input bias current.
Let us know if you need anything else.
Is it fine to use a Open collector and switch of the Transistor ,please let me know with regards to leakage current when DISABLE pin is connected to Hi-Z .
Please let me know the internal circuit connection ,is it a resistor divider circuit used to fix the voltage .
With best regards and wishes
I disagree wrt 5V or +/-5V table. If you run the part on 12V, there is 12V across the part.
The +/-5V table has 10V across the part, so I would use those numbers. HOWEVER,
the abs max is 12.6V, so if you run the part on 12V and your regulator is a little high,
you have violated the abs max and the part may fail.
Apologies on my first reply. Harry is correct.
Thanks Harry for this one.
What i meant was +/-5V supply table not +5V because +/-5V is equivalent to +10V which is closer to +12V.
As for the leakage current and the DISABLE pin, i will get back to you as soon as possible.
Thank you for the valuable information .
What does Table 5 look like when operating at +10V or +12V .
It will great if you could let me know there internal circuit and how it is biased .
Do you have any update with regards to this issue .
The DISABLE pin can be configured depending on the supply voltage you apply. When the DISABLE pin is supplied 2.6V below the positive supply(low), it activates the high impedance state of the part. Please see table below for convenience.
I hope this helps.
Thankyou for the information .
I am planing to use the simulation model SPICE and verify the working .
The symbol of AD8099 seems to rather different(Pin Configuration) from actual device .
This is on Analog device simulator SIMPLIx .
Could you please let me know there is anything to specific .
