Hi Paul,
I have a question regarding LMP7721 application.
Recently I found below application note of the LMP7721 used as a charge amplifier from a third party.
(https://sites.google.com/site/exergylabs/pca-boosterpack/schematic)
My question is, they used LMV796 before signal being sent to ADC. Is there any side effect of this circuit, specially when LMP7721 is implemented as a Trans-impedance configuration for low current measurements? Anyway, what are the advantages of using output buffer circuit ?
Thanks
