  A radiation-hard quad-channel 12-bit 40 MSPS pipeline analog-to-digital
converter (ADC) has been designed for the trigger readout electronics Phase-I
upgrade of the ATLAS Liquid Argon calorimeter, at the CERN Large Hadron
Collider. The final version of the custom design, fabricated in a commercial
130 nm CMOS process, is presented and found to meet the system requirements for
analog performance and radiation tolerance. The procedure for quality control
of 17200 ADCs is described and the results are presented.
