App note: Signals with zero offsets

Dealing with zero offsets signals tackled in this app note from Murata. Link here (PDF) Many transducer outputs exhibit a dc offset voltage when the output level would normally be expected to be zero Volts (corresponding to a display reading of “000”). As an example, consider a pressure transducer whose output levels of 1.0Vdc to […]

App note: Analog common and Reference IN-OUT

App note on Murata’s Digital panel volt meters analog common and reference pins. Link here (PDF) Perhaps the least understood I/O pin on all DMS Series DPM’s is ANALOG COMMON. The confusion surrounding this pin is not unjustified since it should be left open, i.e., have no external connections, in the vast majority of normal […]
