The ACNT-H790 isolation amplifiers are designed for current and voltage sensing in electronic power converters for applications including motor drives and renewable energy systems. In a typical motor drive implementation, current flows through an external resistor and the resulting analog 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 For general applications, the ACNT-H79A (±1% gain tolerance) and the ACNT-H790 (±3% gain tolerance) are recommended. The ACNTH790 offers wide 14.2mm creepage and clearance with a high common-mode transient immunity of 15kV/μs. These features allows the ACNT-H790 to provide the precision and stability needed to accurately monitor motor current in high noise motor control environments, providing for smoother control (less “torque ripple”) in various types of motor control applications. The ACNTH790 operates from a single 5 V supply and provides excellent linearity and dynamic performance of 60dB SNR. With 200kHz bandwidth, 1.6 μs fast response time, the ACNT-H790 captures transients in short circuit and overload conditions. Combined with superior optical coupling technology, the ACNT-H790 uses sigma-delta (Σ-Δ) analog-to-digital modulation, chopper stabilized amplifiers, and a fully differential circuit topology to provide unequaled isolationmode noise rejection, low offset, high gain accuracy and stability. This performance is delivered in a compact, autoinsertable 14.2mm Stretched SO-8 package that meets worldwide regulatory safety standards.
