An integrated circuit arrangement for a microphone, microphone system and method for adjustment of one or more circuit parameters of the microphone system

摘要

An integrated circuit arrangement (20) for a microphone (12) comprises an amplifier circuit (22) and a control unit (30). The amplifier circuit (22) comprises a first switchable network circuit (26) for adjusting a amplifier current of the amplifier circuit (22). The first switchable network circuit (26) comprises a plurality of switches (sw1, swx), which are each provided with a first control terminal of the first switchable network circuit (26) are coupled. The control unit (30) is connected to the first control terminal of the first switchable network circuit (26) configured and is coupled for this purpose, an adjustment of the respective switch (sw1, swx) of the first switchable network circuit to control.
