4 Amps integrated and the pins can undertake 100V

Hello Sean,

  I am not clear on what an "integrated 4 amps" device might be.  Please be more descriptive of what type of IC you are inquiring about.  What type of circuit is being designed? 

Please add as much detail as possible. 

Thank you,

~Leonard  

Hi Leonard, 

The amp will be used on the design current sensing for LM5170, the DCDC input voltage is 48-72V Vin. Thanks a lot! 

Hi Sean,

  Now I understand, you want 4 AMPLIFIERS in one package, I first read this as a CURRENT requirement of 4 Amps and did not understand what device was to handle 4 amperes.

An OpAmp expert will be assisting now.

Regards,

~Leonard
