The Phase-II Upgrade of the ATLAS Muon Spectrometer to the High Luminosity LHC (HL-LHC) requires an efficient trigger and readout system for the Monitored Drift Tube (MDT) chambers. For this purpose, new front-end electronics have been developed including an 8-channel amplifier shaper discriminator (ASD) chip built in 130 nm GF CMOS technology. Using pre-production chips, this presentation discusses the overall performance of these chips as well as the dependence on programmable parameters. Moreover, the uniformity between preproduction chips and the first batch of production chips is shown. These test results are used to define the acceptance criteria for the series testing which is planned for winter 2021. For this series testing a new tester is necessary. Its behavior is studied by retesting all chips with this tester and comparing the corresponding results with those of the previous tester.
