  • Current clamp circuit
    Patent number: 6433610
    Abstract: A current clamp circuit which can easily restrict an output current externally in an output current amplifier circuit using a current buffer IC, is provided. The current clamp circuit 10 restricts the output current in the output current amplifier circuit 20 for amplifying the output current by using the operational amplifier 2 and the current buffer IC 1, wherein the resistor 4 is connected to the output terminal of the current buffer IC, and the output current restriction unit for restricting the output current is connected to the current buffer IC 1 and the resistor 4 in parallel.
