NHD-0420CW-AB3 max low voltage supply?
« on: October 14, 2017, 02:55:37 PM »
Hi, I'm new to Newhaven, using a NHD-0420CW-AB3.  The data sheet says I can tie REGVDD low and supply "2.8V," but 2.8 is kind of an odd number.  Can I officially use 3.0V or 3.3V?  The cover page of the datasheet says "2.4V~5.5V Supply Voltage."  What exactly does that mean?  What is the max recommended voltage when REGVDD is low?

Thanks,

Jeff

For 3.3V operation you can pull the REGVDD low, the max voltage at this level will be ~3.6V
