摘要： An acquisition device and corresponding method for operating the acquisition system are provided. Generally, during operation a plurality of input signals are filtered and multiplexed. The multiplexed input signals are then applied to an amplifier stage; however, when a clamping condition for the amplifier stage occurs, a buffer is switched into a signal path between a multiplexer and an amplifier stage so as to generally reduce the current draw on the input filters.
