I have a need for a multipurpose current sense amplifier. Our current circuit uses a LT1999-50 and works fine using the reference voltage generated from the chip,
but we are trying to combine designs where another current sense is not bidirectional. Is it OK to ground the REF pin to use the full range of the output of the device in a unidirectional fashion?
Due to supply chain issues our choices are small, but if there is a recommendation to use another device that would be fine as well, but at this point I would really like to know if the REF pin can be grounded.
