  • Patent number: 5668494
    Abstract: An electronic driver circuit for low-impedance loads, being of a type which comprises an input terminal (IN) to which a voltage signal (Vin) is applied for alternate transfer to an output, and a plurality of output terminals (OUTi), each connected to a corresponding electric load (2), further comprises, between the input terminal and the output terminals, a single operational amplifier (3) having multiple output stages (7), one for each output terminal (OUTi). The operational amplifier (3) is of the single-ended or fully differential multistage type and allows each load to be driven alternately by activation of the corresponding output stage (7i).
