Part Number: OPA625 Other Parts Discussed in Thread: OPA863 , OPA810 Trying to use the BOM cross tool to match up to the ADA4807-1, it came back with only the OPA625 which looks about right AC wise, but
The ADA4807-1 is +/-5V capable, while the OPA625…
Hi,
the datasheet clearly says that the input voltage must no go below the negative supply voltage. But this would be the case in your circuit, if the input offset voltage results in a voltage at the -input of OPAmp which is slightly negative compared…
Hello Alec
I am OK with your explanation. I try 100/1kohm for the simulation. The result is much better.
Due to I already try to balance the impedance at Invert Input and Non-Invert Input? I think the major is input offset current rather than input bias…
At the beginning, I though a high speed amplifier is necessary. Now I don't really think a 300MHz amplifier is necessary. I would like to try OPA625 with 100MHz bandwidth. But due to its mode control, I have to do a little modification on the layout.…
Hi Ann,
Here is a link to a comparison table for the OPA863, OPA863A, and OPA625: https://www.ti.com/compare-products/?id=72&type=GPT&partList=OPA863A,OPA863,OPA625&columnList=89,480,1261min,1261max,23typ,512,511,22typ,967typ,7typ,1typ,2max,78,2192,1498…
Part Number: OPA625 What would you recommend for this :-
I need a new opamp to act as a buffer before entering the ADC we use.
Need dual supply +/-5v and able to deal with its input being its rails. (Not able to stop the TIA feeding it from saturating…
Part Number: OPA625 Other Parts Discussed in Thread: ADS124S08 , OPA320 , OPA350 , OPA333 Dear Forum Members, I'm writing to you regarding a design problem: We'd like to use the ADS124S08 in one of our products (i.e. sensor signal conversion) and besides…
Other Parts Discussed in Thread: OPA625 , TINA-TI According to OPA625 datasheet the nominal input bias current in High-Drive mode is +2uA, and the input offset current is 20nA. While simulating the SPICE model of OPA625 in TINA-TI I've noticed that the input…
