Title: Bias circuit for audio amplifier
Inventor: ITO HISASHI
IPC: H03F1/00
Filed: 2000-07-11
Abstract: PROBLEM TO BE SOLVED: To provide a bias circuit for audio amplifier that prevents a noise sound from being produced from a speaker when supply of power is stopped. SOLUTION: When a power supply is supplied to the bias circuit normally, since a base level Vb2 of a 2nd transistor (TR) 2 is greater than a base level Vb1 of a 1st TR 1, a 7th TR 7 is nonconductive and no effect is given onto the operation of an output circuit of an audio amplifier to which the collector of the 7th TR is connected. At interruption of power, the base level of the 2nd TR 2 is rapidly decreased from the base level of the 1st TR 1 and a relation of Vb1>Vb2 holds before a bias voltage of an input stage of the audio amplifier exceeds a common mode input voltage range, and the 2nd TR 7 is conductive thereby stopping the operation of the output circuit of the audio amplifier.
