Claim 5:
6. The IC package of claim 1, wherein the resistance detector comprises:
a first current source configured to source a first current;
a first switch coupled between the first current source and the pin;
a second current source configured to source a second current, the second current being different from the first current;
a second switch coupled between the second current source and the pin;
a first sample-and-hold circuit having an input coupled to the pin;
a second sample-and-hold circuit having an input coupled to the pin; and
an analog-to-digital converter (ADC) having one or more inputs coupled to an output of the first sample-and-hold circuit and to an output of the second sample-and-hold circuit.
