Title: CIRCUIT ARRANGEMENT AND METHOD OF OPERATING SUCH CIRCUIT ARRANGEMENT
Abstract:
In order to provide a circuit arrangement (100; 100'; 100') for use in a data transmission system comprising at least one input stage (IS) being connected downstream of at least one bus system (CB), in particular of at least one C[ontroller]A[rea]N[etwork] bus system, the input stage (IS) comprising at least one resistive ladder (RL) for dividing the input signals; and at least one amplifier stage (AS) connected downstream of the input stage (IS), as well as a corresponding method with improved common mode range and with better H[igh]F[requency] performance, it is proposed that that the voltage range of the amplifier stage (AS) is limitated to a defined maximum voltage, in particular to the supply voltage (VCC).
