The ACPL-7900-000E is a Precision Miniature Isolation Amplifier designed for current sensing and voltage sensing in electronic power converter applications such as motor drives and renewable energy systems. In a typical motor drive implementation, current flows through an external resistor and the resulting analogue voltage drop is sensed by the isolation amplifier. A differential output voltage that is proportional to the current is created on the other side of the optical isolation barrier. Combined with superior optical coupling technology, the amplifier implement sigma-delta analogue-to-digital converter, chopper stabilized amplifiers and a fully differential circuit topology to provide unequalled isolation-mode noise rejection, low offset, high gain accuracy and stability.
