Claim 8:
9. The load driving circuit as claimed in claim 1, wherein the load driving circuit comprises k output amplifiers, k being an integer of 2 or more,
wherein the detection circuit:
comprises a selection switch selecting, in order, each of k mirror current pairs respectively generated by the k output amplifiers and respectively formed by a first mirror current with respect to the current flowing in the one of the first output-stage transistor and the second output-stage transistor and a second mirror current with respect to the current flowing in the other of the first output-stage transistor and the second output-stage transistor, and
respectively generates the first current and the second current as mirror currents with respect to the first mirror current in the mirror current pair selected by the selection switch, and respectively generates the third current and the fourth current as mirror currents with respect to the second mirror current in the mirror current pair selected by the selection switch.
