ACPL-C79A-000E

The ACPL-C79A-000E is a precision miniature Isolation Amplifier designed for current and voltage sensing in electronic power converters in 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. The product operates from a single 5V supply and provides excellent linearity and dynamic performance of 60dB SNR. With 200kHz bandwidth, 1.6μs fast response time, the product capture transients in short circuit and overload conditions. The high common-mode transient immunity (15kV/ms) of the ACPL-C79A provides the precision and stability needed to accurately monitor motor current in high noise motor control environments.
