LM4250: END OF LIFE LM4250CN

ANDRE MOREIRA

Part Number: LM4250

I would like to know which electronic component could be used in place of the LM4250CN and which contains the same electrical characteristics. 
Which PartNumber does Texas Instruments recommend to be a replacement for the LM4250CN?
I thank the help of all you

Hi Andre,

The LM4250 is a fairly unique device and we're not sure there is a direct replacement for it.

However, many modern amplifiers can achieve similar (or better) performance metrics than the LM4250 when configured in basic topologies. Could you let us know a little more about the circuit configuration you're using the LM4250 in?

Hello Collin !!!
Thank you for having responded.
The configuration is applied to a high impedance instrumentation amplifier for use in a pH electrode. 
I also use it because it has low current consumption electric characteristics.
Do you have any other information you want to know?
thank you so much !! see you later
