The high-luminosity phase of the Large Hadron Collider will provide 5-7 times greater instantaneous and total luminosities than assumed in the original design of the ATLAS Liquid Argon Calorimeters and their readout system. An improved trigger system with a higher acceptance rate of 1 MHz and a longer latency of up to 60 micro-seconds together with a better radiation tolerance require an upgrade of the readout electronics. Concepts for the future readout of the 182,500 calorimeter channels at 40-80 MHz and 16 bit dynamic range, and the development of low-noise, low-power and high-bandwidth electronic components will be presented. These include ASIC developments towards radiation-tolerant low-noise pre-amplifiers, analog-to-digital converters up to 14 bits and low-power optical links providing transfer rates of at least 10 Gb/s per fiber.
