Abstract
The 13500 channels of the NA48 liquid-krypton electromagnetic calorimeter r eadout electronics were put into operation in 1997. The digitizer electroni cs employs a new gain switching technique that expands the dynamic range of a standard 10-bit ADC to 14 bits at 40 MHz sampling rate employing a custo m-developed integrated circuit (KRYPTON). The KRYPTON has been fabricated i n 1.2 mu m BiCMOS technology and was successfully developed together with i ndustry on a short timescale. The performance and the experience from the f irst year of the operation of the liquid-krypton calorimeter electronics wi ll also be briefly discussed. (C) 1998 Elsevier Science B.V.
