Hewlett-Packard’s Isolated A/D Converter delivers the reliability, small size, superior
isolation and over-temperature performance motor drive designers need to accurately
measure current at half the price of traditional solutions.
CAUTION: It is advised that normal static precautions be taken in handling and assembly of this component to
prevent damage and/or degradation which may be induced by ESD.
