AB Instrumentation amplifiers and voltage controlled current sources have been designed by using single operational amplifiers (OPA124, TLE2071 and OPA627). Their performance has been evaluated in the laboratory and under neutron radiation. On line measurements of the offset voltages, offset currents, closed loop gain, CMRR and bias currents were performed on the amplifiers. The current sources were set to a constant value and the current was monitored on-line. The radiation tolerance of commercial voltage references has also been investigated.The radiation was performed out in ITN (Portugal) research nuclear reactor. In comparison to previous experimental campaigns the gamma radiation has been reduced by a factor 15 for a given neutron dose. This is achieved thanks to a recently constructed facility for neutron beam extraction
