Load circuit and amplifier

摘要

Problem to be solved: to provide a load circuit for reducing power consumption.A load circuit inserted between the input terminals of an amplifier, and a switch circuit for switching between the resistance and the connection and disconnection of the resistor between the input terminals and after a predetermined period of time after the power supply to the preceding stage is turned on The load circuit is provided with a control circuit for controlling switching of the switching circuit to the disconnection between the input terminals.Diagram
