sa87 Posted June 20, 2012 Report Share Posted June 20, 2012 I need to supply varying voltage input to an opam circuit. Voltage input should be given by the computer and I need a way to turn the given computer data into opam input. Please help. Quote Link to comment Share on other sites More sharing options...
Kevin Weddle Posted June 20, 2012 Report Share Posted June 20, 2012 The serial port is often used for downloading data to devices. A demutiplexar can convert serial data into parallel data output. A DC to AC converter is probably the simplest solution for a voltage selector. Quote Link to comment Share on other sites More sharing options...
