wvengineer Posted September 7, 2006 Report Share Posted September 7, 2006 I'm doing a project for this plant...a wireless interface. Anyways I'm also adding a low battery state alarm for remote nodes. This will be implemented by using a LTC1440. My problem is that the output states are like 50mV and 5-9V. I need to convert the 50mV into a negative 3-12V for rs-232 and it needs to remain a low power circuit so that the battery state doesn't drain the battery quicker than the modems. Any low power converters that are popular? Quote Link to comment Share on other sites More sharing options...
