Abstract

Circuit arrangement with an operational amplifier This circuit arrangement has the property of an amplifier with a set or adjustable non-inverting gain and contains an opamp (3) having an a non-inverting and an inverting input (31, 32) as well as an output (33) which is also a signal output (A) of the circuit arrangement, and a current copier (8) having a current input and a current output. The noninverting input (31) is connected to a first reference potenial (P1) and the output (33) via a first resistor (1) to the inverting input (32). The input (E) of the circuit arangement is connected via a second resistor (2) to the curent input of the current copier (8) the current output of which is connected to the inverting input (32). The output section of the current copier is connected to a second reference potential (P2) and its input section to the first reference potential.
