PURPOSE:To provide the amplifying circuit with clip which can be operated at a high speed and has a simple circuit constitution. CONSTITUTION:An input voltage VIN, a lower limit clip voltage VL, and an upper limit clip voltage VH are impressed to input terminals 2, 3, and 4 respectively. These voltages are compared with one another, and an output voltage VOUT=VIN is set in the case of VL<VIN<VH, and VOUT=VH is set in the case of VH<=VIN, and VOUT=VL is set in the case of VIN<=VL. Thus, the saturation of an output stage is avoided, and the responsiveness of the output voltage to the input voltage is improved, and the circuit is operated at a high speed. |
