Abstract	To meet new TDAQ buffering requirements and withstand the high expected radiation doses at the high-luminosity LHC, the ATLAS Liquid Argon Calorimeter readout electronics will be upgraded. Developments of low-power preamplifiers and shapers and of a low-power 40 MHz 14-bit ADCs are ongoing. The signals will be sent at 40 MHz to the off-detector electronics, where FPGAs connected through high-speed links will perform energy and time reconstruction. The data-processing, control and timing functions will be realized by dedicated boards. Results of tests of front-end component prototypes will be presented, along with design studies on the off-detector readout system.
