PROBLEM TO BE SOLVED: To provide a current clamp circuit that can easily apply current clamping to an output current amplifier circuit employing a current buffer IC from the outside of the current amplifier circuit. SOLUTION: In the current clamp circuit 10 that limits an output current of the output current amplifier circuit 20 by using an operational amplifier 2 and the current buffer IC, a resistor 4 is connected to the output stage of the current buffer IC 1 and a load current limit means is connected in parallel with the current buffer IC 1 and the resistor 4 to limit a load current thereby clamping the output current. |
