  The ICARUS T600, a liquid argon time projection chamber (LAr-TPC) detector
mainly devoted to neutrino physics, underwent a major overhauling at CERN in
2016-2017, which included also a new design of the read-out electronics, in
view of its operation in Fermilab on the Short Baseline Neutrino (SBN) beam
from 2019. The new more compact electronics showed capability of handling more
efficiently the signals also in the intermediate Induction 2 wire plane with a
significant increase of signal to noise (S/N), allowing for charge measurement
also in this view. The new front-end and the analog to digital conversion (ADC)
system are presented together with the results of the tests on 50 liters liquid
argon TPC performed at CERN with cosmic rays.
