Abstract

An amplifier arrangement with a Class D design is proposed which has a low-pass filter device comprising a first inductor and a second inductor The first inductor is arranged between a first load output and a load and the second inductor is arranged between a second load output and the load. The first and second inductors are coupled to one another so that the total inductance of the two inductors is greater than the sum of the individual inductances of the two inductors and also less than or equal to 1.95 times the sum of the individual inductances of the two inductors.
