摘要： An amplifier circuit comprises a first and a second two-input differential input circuit. The first input circuit has first and second input terminals and the second input circuit has third and fourth input terminals. The first input terminal is connected to a first circuit input, the fourth input terminal is connected to a fourth circuit input. Programmable circuitry is provided for selectively connecting the second and third input terminals either to the second and third circuit inputs or to the fourth and first inputs.
