Abstract	The LHCb Outer Tracker is composed of 55 000 straw drift tubes. The requirements for the OT electronics are the precise (1 ns) drift time measurement at 6 % occupancy and 1 MHz readout. Charge signals from the straw detector are amplified, shaped and discriminated by ATLAS ASDBLR chips. Drift-times are determined and stored in the OTIS TDC and put out to a GOL serializer at L0 accept. Optical fibres carry the data 90 m to the TELL1 acquisition board. The full readout chain performed well in an e- test beam.
