ABSTRACT Hybrid assemblies of LHC1 read-out chips and 300 um thick silicon pixel detectors have been tested with a 120 GeV/c pion beam at the CERN SPS. The equivalent noise charge at the input of the preamplifier is 200 e. The particle detection efficiency is higher than 99.9%. A 30 ns wide efficiency plateau is reached for a 60 ns wide trigger pulse applied after a 2 us delay. The 50 um, 500 um pixels yield a spatial precision of 129.4+/-0.2 um in the large pitch direction. In the other direction the precision is 12.2+/-0.2 um for single-pixel clusters.
