  1. Analog-to-digital conversion based on the classic combination of a voltage-to-frequency converter (VFC) with a counter has been around for (many) decades, mainly because it has some durable time-proven advantages. VFC digitization is naturally ...

    The 0- to 20-mA current loop is a reliable means of data communication in industrial applications. These circuits use a precision shunt in the receiver to convert the current signal into a voltage signal. Accidentally connecting the precision ...
