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.
