The electronic circuit having an input stage for pre-amplifying an electrical input signal of the electronic circuit provided by a transducer. The electronic circuit has an output stage for providing a microphone output signal by processing an output signal of the input stage. The electronic circuit has an adjustable output load arranged and configured for setting a current draw of the output stage. Additionally, the electronic circuit has a measurement circuit configured to capture the output signal of the input stage and an automatic control circuit configured to adjust the adjustable output load dependent on the captured output signal of the input stage.
