  2. Circuits Analogue Design Analog Devices ADCMP601 ADG772 ADR390
    In a previous Design Idea, a circuit switches precision dc reference voltages to the noninverting input of a high-speed IC comparator (Reference 1). The circuit uses a 2-to-1 multiplexer that functions in a BBM (break-before-make) fashion. ...
