Claim 0:
1. A differential input circuit, comprising:
a first input voltage protection transistor having a control terminal and a first input terminal of the differential input circuit;
a second input voltage protection transistor having a control terminal and a second input terminal of the differential input circuit;
a first input transistor having a control terminal coupled to the first input voltage protection transistor by a first current path;
a second input transistor having a control terminal coupled to the second input voltage protection transistor by a second current path;
a control terminal drive voltage source coupled to the control terminals of the first and second input protection transistors;
a first feedback path coupled to the control terminal of the first input voltage protection transistor; and
a second feedback path coupled to the control terminal of the second voltage protection transistor.
