Converting to rs-232 voltages

Recommended Posts

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?
